The Tohatsu MFS25DEFTL represents the ultimate tiller-steered outboard experience, combining Tohatsu’s revolutionary lightweight 3-cylinder engineering with premium convenience features in a 20-inch shaft configuration. At 153 pounds, this Generation D model delivers 25 horsepower with the convenience of electric start and integrated power trim/tilt functionality, perfect for deeper transom applications where direct tiller control is preferred. The electric start system eliminates manual rope pulling while the power trim and tilt allows precise engine positioning at the touch of a button.
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 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. 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 keeps batteries charged during extended outings.
The MFS25DEFTL features intuitive power trim and tilt controls integrated into the tiller steering system, allowing operators to optimize engine angle for varying load conditions while maintaining direct throttle and steering control. The twist-grip throttle provides precise speed control while the 20-inch shaft ensures proper cooling water flow for deeper transom installations. Manual recoil starter provides reliable backup starting capability, ensuring dependable operation in any situation.
Built for boaters who demand both premium features and hands-on control, the MFS25DEFTL excels with aluminum bay boats, larger fishing boats, deeper transom applications, and craft where precise tiller maneuvering is preferred. The included 25-liter fuel tank provides extended range for longer excursions. 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, the MFS25DEFTL delivers the perfect combination of power, convenience, and responsive tiller control for experienced boaters who appreciate the direct connection between operator and engine.
