Yamaha T25 High Thrust

The Yamaha T25 High Thrust delivers muscle without the bulk, utilizing Yamaha’s award-winning, ultra-lightweight 432cc twin-cylinder powerhead and modifying it specifically for heavy-load applications. While traditional high-thrust motors carry a massive weight penalty, the T25 boasts an incredible power-to-weight profile. By pairing this lightweight SOHC block with an enlarged gearcase and a specialized low-pitch propeller, this motor produces exceptional structural leverage to push large, high-drag hulls with ease.

Engineered with Electronic Fuel Injection (EFI) for battery-less starting, standard power trim and tilt, and precise microprocessor control, the T25 is the premier choice for mid-sized pontoon configurations and maneuvering sailboats. Its advanced design ensures clean, smoke-free operation, exceptional low-end torque, and reliable responsiveness in tight slipways.
