The Tohatsu MFS25DS represents pure outboard engineering excellence, delivering 25 horsepower in Tohatsu’s revolutionary Generation D lightweight design without unnecessary complexity. At just 128 pounds, this 3-cylinder powerhouse achieves the lightest weight in its class while maintaining the robust reliability Tohatsu is renowned for. The straightforward manual start configuration ensures dependable operation with minimal maintenance, making it perfect for boaters who appreciate simplicity and proven performance.
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, consistent performance, and superior fuel economy without requiring electrical power to operate. 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 for charging electrical systems while running.
The MFS25DS features Tohatsu’s redesigned standard tiller handle with integrated four-step variable idle control (750-1050 RPM), forward-neutral-reverse shifter, throttle friction adjustment, and engine stop switch. The twist-grip throttle provides precise speed control while the 15-inch shaft length makes this motor ideal for standard transom applications including aluminum fishing boats, jon boats, skiffs, and smaller recreational craft. Manual recoil starting with decompression release ensures easy, reliable starts every time.
Built for boaters who value simplicity, reliability, and exceptional value, the MFS25DS excels with aluminum boats, fishing applications, and situations where straightforward operation is preferred over complex features. 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 dating back to 1956, the MFS25DS delivers outstanding performance, legendary reliability, and exceptional fuel economy in a no-nonsense package that prioritizes what matters most: getting you on the water and back home safely.
