At 153 pounds, this Generation D model delivers 25 horsepower with the convenience of electric start and integrated power trim/tilt functionality, making it perfect for deeper transom applications requiring a 20-inch shaft. The electric start system eliminates manual pulling while the power trim and tilt allows precise engine positioning for optimal performance across varying conditions.
Advanced battery-less Electronic Fuel Injection technology ensures reliable operation across the entire 5,000-6,000 RPM range, delivering exceptional fuel efficiency at 2.3 gallons per hour at wide-open throttle while maintaining EPA and CARB 3-Star emission compliance. This sophisticated EFI system provides smooth acceleration, easier cold starts, and superior fuel economy in all weather conditions. The 500cc displacement with optimized 61mm x 57mm bore and stroke delivers impressive torque characteristics specifically tuned for efficient 25 horsepower output.
The newly designed torpedo-shaped gear case reduces drag and improves hydrodynamic flow, while repositioned engine mounts minimize vibration for quieter operation. The optimized 2.17:1 gear ratio maximizes low-end torque for efficient planing and excellent acceleration characteristics. Engineering improvements include dual water intakes for enhanced cooling, transparent fuel filter with floating indicator ring, and robust 12V, 210W, 17.5A alternator output that easily handles modern electrical demands.
The MFS25DETL features intuitive power trim and tilt controls allowing operators to optimize engine angle for varying load conditions, sea states, and performance requirements. The 20-inch shaft length makes this motor ideal for bay boats, larger center consoles, deeper transoms, and applications requiring proper water immersion for optimal cooling and performance. Manual recoil starter provides reliable backup starting capability, ensuring dependable operation in any situation.
Built for versatility and premium performance, the MFS25DETL excels with aluminum bay boats, fiberglass center consoles, larger fishing boats, and deeper transom applications. The included 25-liter fuel tank ensures extended range for longer fishing trips and coastal cruising. High-solid paint coating provides superior protection against UV rays and saltwater corrosion. With Tohatsu’s comprehensive 5-year limited warranty and proven Japanese engineering excellence dating back to 1956, the MFS25DETL delivers the perfect balance of power, convenience, efficiency, and reliability for serious boaters who demand premium features and uncompromising performance in a long-shaft configuration.
