Abstract

The Marine Engine Mechanical Accelerator was developed to address the performance inefficiencies, safety risks, and economic limitations of traditional nylon-based throttle systems in pump boats. Existing acceleration mechanisms suffer from frequent wear, inconsistent speed control, and high maintenance costs, which negatively impact fishermen and small-scale maritime operators. This study introduces a pedal-controlled mechanical accelerator designed to enhance maneuverability, operational safety, and cost efficiency. Evaluations from 50 students and 5 marine experts confirmed its high functionality (4.90), cost-effectiveness (4.84), and aesthetic design (4.84). Key findings indicate that the system significantly improves stability, reduces mechanical failures, and enhances fuel efficiency, proving its techno-economic viability. The use of locally available and durable materials lowers long-term maintenance expenses while ensuring affordability and ease of adoption. By reducing fuel consumption and downtime, the accelerator increases economic benefits for boat operators, making it a sustainable and scalable innovation. Future research should explore advanced material integration and mass production strategies to enhance durability and commercial viability. This innovation presents a transformative solution for coastal communities, fostering safer, more cost-effective, and environmentally sustainable marine transportation.
