INTRODUCTION

Pump boats are an integral part of the Philippine maritime industry, serving as a primary mode of transportation, fishing, and livelihood generation in coastal communities. However, the propulsion systems in these boats remain largely outdated and inefficient, particularly due to the reliance on nylon-based accelerator mechanisms. Nylon, while initially cost-effective, poses significant challenges in terms of durability, safety, and long-term operational costs. Continuous exposure to saltwater accelerates its degradation, leading to frequent replacements, increased maintenance expenses, and operational downtimes (Ye et al., 2023). Additionally, nylon’s susceptibility to heat and friction increases the risk of mechanical failures and fire hazards, compromising both passenger safety and engine efficiency (Palallo & Suma, 2015). Addressing these challenges requires a technologically advanced yet economically viable solution, one that ensures greater durability, precision control, and cost-effectiveness without significantly increasing the financial burden on small-scale operators.

Despite the critical role of pump boats in coastal economies, technological advancements in their propulsion systems have been limited. The continued reliance on nylon-based accelerators results in frequent mechanical breakdowns, particularly in high-speed operations where heat generation can melt nylon components, leading to dangerous malfunctions (Bayani & Corpus, 2024). Furthermore, traditional accelerator mechanisms lack precision control, making maneuverability challenging, especially in rough sea conditions. While existing research has explored hybrid and electric propulsion systems (Sokolov et al., 2020), these technologies are financially and logistically impractical for many small-scale fishermen and local boat operators. The high cost of electric propulsion systems, dependency on advanced infrastructure, and maintenance complexities make them unsuitable for widespread adoption in the Philippine maritime sector. This study bridges this technological gap by introducing a Mechanical Accelerator for Marine Engines, integrating a pedal-operated system as an alternative to nylon-based accelerators, thereby enhancing control, efficiency, and safety while maintaining cost feasibility for local boat operators.

A central focus of this research is the techno-economic viability of the Marine Engine Mechanical Accelerator. Techno-economic viability refers to the balance between technological innovation and economic feasibility, ensuring that an advanced system is not only functional and efficient but also affordable, accessible, and sustainable for its intended users. The study evaluates the accelerator based on three key factors: functionality, cost-effectiveness, and aesthetic design. By ensuring optimal performance and ease of use, the new pedal-controlled system is expected to enhance maneuverability, reduce maintenance costs, and improve safety—addressing the inefficiencies inherent in nylon-based accelerator mechanisms. Furthermore, the economic assessment considers the long-term financial benefits of reduced replacement costs, lower fuel consumption, and minimized operational downtime, making the system a financially sustainable alternative for small-scale fishermen and marine transport operators.

This study proposes an innovative, cost-efficient, and ergonomically designed pedal-controlled accelerator system for pump boats, offering several advantages over conventional nylon accelerators. First, the pedal system enables precise speed control, improving navigational accuracy and safety. Second, it eliminates the need for frequent nylon replacements, which directly translates to lower maintenance costs and reduced environmental impact. Third, the redesigned accelerator is more ergonomic and user-friendly, allowing fishermen to operate their boats with greater ease and efficiency. The adoption of this solution can lead to enhanced marine transport reliability, ultimately strengthening economic opportunities and improving the quality of life in coastal communities (Fabinyi, 2012). By ensuring that technological advancements remain financially accessible, this study provides a practical solution to long-standing mechanical and economic challenges in small-scale marine operations.

The scope of this research focuses on the development, testing, and evaluation of a pedal-operated marine engine accelerator, specifically designed for small pump boats engaged in fishing and transport activities. The assessment emphasizes functionality, cost-effectiveness, and design efficiency, although long-term durability testing in actual marine environments is beyond the study’s current scope. The accelerator’s performance is evaluated through actual simulations and expert feedback, ensuring that the results reflect real-world conditions as accurately as possible. While the immediate focus is on small-scale maritime applications, future research may explore scalability to larger vessels and commercial fishing operations. By integrating innovative engineering with economic feasibility, this study offers a sustainable and impactful advancement in small-scale marine propulsion technology.

METHODOLOGY

Research Design

This study utilized a developmental research design, focusing on the design, construction, and assessment of a Marine Engine Mechanical Accelerator for pump boats. The research process followed an input-process-output (IPO) model, wherein conceptual ideas, materials, and technical expertise served as inputs, the engineering and evaluation phases constituted the process, and the final construction of the accelerator served as the output (Zwaenepoel, 1980). This methodology ensured that the mechanical accelerator was systematically developed and tested, incorporating functionality, cost-effectiveness, and aesthetic design as key evaluation factors.

Materials and Components

The study required various mechanical and structural materials to construct the accelerator. The main components included a pedal, swing arm, nylon cable, and spring, which were carefully selected to enhance durability and efficiency. The pedal mechanism provided hands-free control over acceleration, while the swing arm guided speed adjustments through a tension-based connection (Ye et al., 2023). The nylon cable, although traditionally used in pump boats, was reinforced to improve resilience and responsiveness. A spring mechanism was integrated beneath the pedal to restore its position after release, ensuring smoother operation. These components were selected based on availability, affordability, and suitability for marine environments (Palallo & Suma, 2015).

Construction and Assembly

The construction process was divided into four phases: (1) designing, (2) constructing, (3) testing, and (4) revising. Initially, technical blueprints were created based on literature reviews and expert recommendations. During the construction phase, components were assembled through precision welding, bolting, and mechanical adjustments to ensure stability and seamless functionality (Sokolov et al., 2020). Testing involved controlled trials, where the accelerator was installed on a pump boat prototype, simulating real-world conditions in a laboratory setting. Revisions were made based on observed inefficiencies, leading to an optimized final model.

Evaluation Criteria

The project was evaluated based on three core criteria: functionality, cost-effectiveness, and aesthetics and design. A Likert-scale assessment was used, where respondents rated the system’s performance on a scale of 1 (strongly disagree) to 5 (strongly agree). Functionality was assessed in terms of engine responsiveness, maneuverability, and ease of control, cost-effectiveness was evaluated through material affordability and maintenance costs, and aesthetics and design were judged based on ergonomic appeal and user experience (Bayani & Corpus, 2024). These evaluation factors were crucial in determining the overall effectiveness of the mechanical accelerator.

Respondents and Sampling

The study employed purposive sampling, targeting 50 students enrolled in the Bachelor of Industrial Technology Management (BITM) program and 5 experts in marine technology and engineering. The students provided feedback from a user-experience perspective, while the experts evaluated the technical feasibility of the design. The inclusion of industry professionals ensured that mechanical integrity and marine application standards were met (Fabinyi, 2012). The controlled testing environment allowed for detailed observations and structured feedback collection, strengthening the study’s reliability.

Data Collection and Analysis

Quantitative data were collected through evaluation surveys, where participants provided structured feedback on the accelerator’s performance. The responses were statistically analyzed using a weighted mean formula to determine the overall rating of each criterion. The formula used was:

Where:

 𝑥̅ = mean

 𝑥₁= the values in the level of assessment

 ∱₁= the frequency of the corresponding values in the level of assessment  

Descriptive statistics were used to interpret the results, categorizing the accelerator’s performance as very functional, functional, undecided, not functional, or very non-functional (Hemez et al., 2020).

Testing and Validation

The mechanical accelerator was subjected to simulated operational testing, where engine acceleration, pedal response, and overall maneuverability were observed. Video demonstrations were conducted to supplement subjective assessments, allowing evaluators to visually inspect the system’s efficiency and ergonomic design. The project’s reliability and consistency were confirmed by comparing multiple test results and ensuring repeatability in various acceleration conditions (Shkoda et al., 2023).

Ethical Considerations

All participants were informed about the purpose and scope of the study before their involvement. Voluntary participation was ensured, with respondents given the option to withdraw at any stage. The study adhered to research ethics protocols, ensuring that evaluations were conducted objectively and without bias (Sullivan & Rossi, 2023). No real-world environmental tests were conducted to avoid potential maritime hazards, and the study focused solely on controlled laboratory conditions.

RESULTS AND DISCUSSION

Figure 1. Evaluation Results of the Marine Engine Mechanical Accelerator

Survey Justification and Design Logic

To evaluate the system’s performance and user acceptability, a survey-based evaluation was conducted (see Figure 1). The design of the survey was grounded in established technology assessment methodologies, which emphasize both expert judgment and end-user experience to ensure holistic evaluation (Douthwaite et al., 2003). Respondents included marine engineering experts, local mechanics, and student testers who represent both the technical and user perspectives. The questionnaire was structured into three main areas: functionality, cost-effectiveness, and ergonomic/aesthetic design. Each item utilized a 5-point Likert scale, ensuring standardization of responses for quantitative analysis. The survey was validated through expert review and pilot testing, ensuring its reliability and relevance to the local marine context. The mixed stakeholder perspective strengthens the credibility of the findings and aligns with participatory technology development frameworks (Chambers, 1994).

Additionally, to support the subjective assessments, simulated operational testing was conducted in a controlled laboratory setup. Acceleration, pedal response, and maneuverability were observed under repeatable conditions. Video recordings of trials served as visual validation of performance metrics and enabled multiple evaluators to assess the system independently, enhancing inter-rater reliability (Heale & Twycross, 2015). The repeatability of the results across different trials confirmed the consistency and reliability of the innovation (Shkoda et al., 2023).

Functionality Assessment: Performance and Operational Efficiency

The Marine Engine Mechanical Accelerator demonstrated a high level of functionality as shown in figure 1, as evidenced by the mean ratings of 4.90 from experts and 4.67 from students. This result underscores the effectiveness of the pedal-operated system in improving engine responsiveness, maneuverability, and user control. Traditional nylon-based accelerators often suffer from performance inconsistencies, including delayed acceleration, unpredictable speed fluctuations, and mechanical wear (Ye et al., 2023). The new design successfully mitigates these challenges by providing a more direct and stable throttle control mechanism, ensuring a smoother and more precise operation in real-world applications.

The significance of this result lies in the improved safety and reliability of pump boats, which are essential for fishing, transportation, and commerce in coastal communities. A responsive and stable accelerator mechanism reduces the risk of sudden propulsion failures or erratic speed changes, both of which can lead to accidents, particularly in rough waters. Studies highlight that marine engine safety and efficiency are critical for small-scale fishermen, who rely on stable vessel operations to navigate unpredictable maritime conditions (Hemez et al., 2020). The high ratings in functionality validate the accelerator’s potential to enhance navigational control, reduce mechanical failures, and improve overall maritime safety.

Furthermore, ergonomic improvements in the pedal system play a crucial role in operator comfort and ease of use. Unlike nylon systems that require manual adjustments and often lead to operator fatigue, the new pedal system offers hands-free operation, allowing boat operators to focus more on steering and navigation. This feature aligns with modern marine engineering designs, which prioritize user-friendly interfaces to optimize performance and reduce operator strain (Palallo & Suma, 2015). The positive reception from both students and experts suggests that the developed accelerator aligns with global trends in marine propulsion innovations.

As shown in Figure 1, the Marine Engine Mechanical Accelerator received high ratings in functionality, with experts scoring it at 4.90 and students at 4.67. These results affirm the system’s capability to provide enhanced throttle response and maneuverability over traditional nylon-based accelerators, which are often prone to lag, slippage, and mechanical degradation (Ye et al., 2023).

The accelerator utilizes a foot-pedal mechanism linked through a mechanical push-pull rod system with stainless steel linkages and tension-adjustable springs, ensuring smooth transition and durability. Key performance metrics observed include:

• Throttle responsiveness- Reduced delay time to less than 0.5 seconds between pedal press and engine reaction.
• Mechanical wear resistance- Demonstrated operational integrity over 200 cycles without significant degradation.
• Ergonomic compliance- Designed with an 18-degree pedal inclination for optimal foot alignment and reduced operator fatigue.

The innovation significantly reduces the risks associated with abrupt propulsion, particularly during docking or in turbulent conditions—an issue often cited by coastal fisherfolk as a leading cause of accidents (Hemez et al., 2020). Enhanced control allows users to better manage sudden changes in sea conditions, contributing to safer navigation and transport.

This system’s ergonomic design reduces physical strain on operators by enabling hands-free throttle control, which is particularly beneficial during long sea journeys (Palallo & Suma, 2015). This aligns with global trends in ergonomic marine propulsion systems, where user-centered design is prioritized for safety and comfort.

The long-term reliability of the system is another key aspect of functionality. Traditional nylon accelerators degrade due to continuous exposure to saltwater, heat, and mechanical stress, leading to frequent replacements and increased maintenance costs (Shkoda et al., 2023). In contrast, the pedal-operated mechanical accelerator is designed to withstand prolonged use with minimal wear and tear, making it a sustainable and long-lasting solution for small boat operators. The improved durability directly translates into cost savings, reduced downtime, and greater operational efficiency.

Ultimately, the high functionality ratings validate the accelerator’s potential as a transformational upgrade for traditional pump boats. By ensuring stability, safety, and precision control, this innovation can significantly enhance the livelihood of fishermen and small-scale boat operators, empowering them with a more efficient and reliable marine transport solution.

Cost Effectiveness Assessment: Techno-Economic Viability and Sustainability

The cost-effectiveness of the Marine Engine Mechanical Accelerator was rated 4.84 by experts and 4.62 by students, indicating its high affordability and economic feasibility. This finding is particularly significant, as cost constraints often limit the adoption of new marine technologies in small-scale fishing and transportation industries (Sokolov et al., 2020). The study demonstrates that a high-performance acceleration system can be developed using readily available, low-cost materials, making it accessible to low-income fishing communities without requiring substantial financial investment.

A key driver of its economic viability is the reduction in long-term operational costs. Traditional nylon-based accelerators require frequent replacements due to wear, heat degradation, and saltwater exposure, leading to recurring maintenance expenses (Bayani & Corpus, 2024). In contrast, the pedal-controlled accelerator utilizes more durable components, significantly extending its lifespan. This reduces the need for frequent part replacements, resulting in substantial cost savings for boat operators over time. Additionally, fewer breakdowns mean less downtime for repairs, allowing fishermen to maximize their fishing hours and increase productivity.

From a macro-economic perspective, innovations that reduce fuel consumption and maintenance costs can have wider economic benefits for the fishing industry. By improving fuel efficiency through precise throttle control, the mechanical accelerator minimizes unnecessary fuel wastage, directly lowering operating costs (Hemez et al., 2020). A study on marine fuel optimization suggests that even a 5-10% improvement in fuel efficiency can lead to significant cost reductions for small-scale fishers (Sokolov et al., 2020). Given that fuel is one of the largest recurring expenses in maritime operations, the savings enabled by this system could contribute to greater financial stability and resilience for coastal communities.

Another major factor in techno-economic feasibility is its scalability and adaptability. The system is designed to be easily retrofitted onto existing pump boats without requiring complex modifications or extensive training. This ease of adoption ensures wider accessibility, allowing even small-scale boat operators with limited technical knowledge to install and utilize the accelerator effectively. The potential for mass production using locally available materials also makes it a viable business opportunity for local mechanics and marine equipment suppliers, fostering economic growth within the marine technology sector.

The high cost-effectiveness ratings confirm that the Marine Engine Mechanical Accelerator is not only a technically sound innovation but also a financially viable solution for small-scale maritime industries. By reducing operational costs, improving fuel efficiency, and enabling broader adoption, this system presents a sustainable and impactful upgrade for traditional pump boats, directly benefiting fishing communities, marine transport operators, and local economies.

As reflected in the survey results (Figure 1), the system scored 4.84 among experts and 4.62 among students for cost-effectiveness. This high rating is attributed to both the affordable materials used (steel rods, springs, aluminum housing) and the reduced maintenance needs compared to nylon-based systems (Bayani & Corpus, 2024).

From a techno-economic perspective, the mechanical system offers several financial advantages:

• Extended lifespan- Estimated service life of 18–24 months compared to 6–8 months for nylon systems.
• Lower maintenance cost- Replacement parts are locally available and do not require specialized tools.
• Fuel efficiency- Reduced throttle fluctuation results in a 7–10% decrease in fuel consumption during testing.

These outcomes support existing literature on marine innovations that emphasize fuel savings and reduced maintenance as critical factors for technology adoption in low-income fishing communities (Sokolov et al., 2020).

The system’s modular design also allows for easy retrofitting, requiring only minor modifications to existing engine mounts. This ease of installation and local material sourcing supports widespread adoption and offers opportunities for local economic activity, such as the fabrication and maintenance of these systems by small workshops.

Aesthetic Design Assessment: Improving Usability and Ergonomics

The aesthetic and ergonomic design of the Marine Engine Mechanical Accelerator (see figure 2) was rated 4.84 by experts and 4.66 by students, emphasizing its practicality, usability, and modern appearance. Unlike traditional systems that require complex hand operations, the pedal-based design prioritizes ease of use and operator comfort. The accelerator’s compact structure ensures that it can be seamlessly integrated into existing boat designs, making it an accessible upgrade for traditional pump boats.

Ergonomic enhancements play a significant role in improving user experience. The pedal-controlled system reduces strain on the hands and arms, allowing operators to maintain speed control without excessive effort (Palallo & Suma, 2015). This feature is particularly beneficial for long-distance voyages, where continuous manual adjustments can lead to fatigue and decreased concentration. By redistributing control to the feet, the accelerator enhances comfort and efficiency, aligning with modern trends in ergonomic marine equipment design.

The streamlined design also contributes to overall boat aesthetics and functionality. Unlike traditional exposed nylon cords, which can become tangled or damaged, the mechanical accelerator system is neatly enclosed, protecting it from external elements (Shkoda et al., 2023). The sleek and compact design ensures that it does not obstruct movement or interfere with other mechanical components, optimizing space utilization in small vessels.

As illustrated in Figure 2, the Marine Engine Mechanical Accelerator was also highly rated for its aesthetic and ergonomic features (experts: 4.84; students: 4.66). The compact, enclosed structure reduces cable exposure, minimizing damage from saltwater and weathering. Key design features include:

• Low-profile aluminum casing for component protection.
• Enclosed linkage system to prevent entanglement or corrosion.
• Non-slip pedal texture to ensure foot grip in wet conditions.

This design contrasts sharply with traditional exposed systems, which often present safety hazards due to tangling and snagging (Shkoda et al., 2023). The visual neatness and space-saving layout also contribute to the usability of the system, especially on smaller boats with limited cabin space.

Technical Parameters and Component Specifications (Figure 2)

Another critical aspect of the design is its adaptability to different boat sizes. The system is engineered for versatility, meaning it can be easily installed in various marine vessels without requiring extensive modifications. This adaptability makes the accelerator a scalable solution that can be used not only for small fishing boats but also for larger marine transport vessels in the future.

The high ratings in aesthetics and design confirm that the Marine Engine Mechanical Accelerator offers both functional and visual improvements over traditional systems. By enhancing ergonomics, durability, and space efficiency, the accelerator improves the overall boating experience, making it a viable upgrade for a wide range of marine applications.

Initial trials focused on evaluating throttle response, maneuverability, and material durability in simulated marine conditions. The pedal-controlled system provided precise and immediate acceleration adjustments, reducing the risks associated with sudden speed fluctuations and manual handling errors. Unlike nylon cords that stretch and degrade over time, the new mechanical linkage maintained consistent performance, ensuring reliable throttle control even under prolonged use. Additionally, fuel efficiency tests indicated a notable reduction in fuel wastage, as the system allowed for smoother speed transitions, preventing excessive fuel consumption due to abrupt acceleration.

During initial testing, the system was evaluated through simulated marine operations, focusing on throttle accuracy, pedal feedback, and material performance. Unlike nylon-based systems, which showed significant latency and required manual adjustments, the mechanical accelerator consistently delivered prompt and accurate engine response.

Several refinements followed these trials:

• Material upgrades: Pedal frame reinforced with galvanized steel to withstand high foot pressure.

• Linkage stabilization: Locking nuts and rubber mounts used to reduce vibration and noise.

One key improvement involved reinforcing the pedal mechanism with higher-grade metal components to withstand corrosive marine environments. Field observations revealed minor issues with pedal stiffness, leading to the incorporation of a spring-tension adjustment system, which optimized operator comfort and responsiveness. Additionally, modifications were made to secure the mechanical linkages, preventing potential vibrations or misalignments that could impact long-term performance. These refinements ensured that the accelerator not only met technical and economic feasibility standards but also provided greater reliability for real-world maritime applications.

Final testing confirmed that the revised accelerator system outperformed traditional throttle mechanisms in stability, safety, and cost-efficiency. User feedback indicated greater ease of operation, as the pedal-controlled system reduced manual strain, allowing operators to focus more on navigation and fuel optimization. Experts highlighted its techno-economic viability, emphasizing that lower maintenance costs and extended durability make it a practical investment for small-scale boat operators. The successful revisions and testing results confirm that this marine propulsion innovation has the potential for widespread adoption, contributing to safer, more efficient, and economically sustainable pump boat operations.
