High Thrust 25 HP


Our 432-cc 25-hp High Thrust outboard delivers the power and grip with exceptional efficiency. This newly redesigned outboard has the best power-to-weight ratio of all high-thrust 25 horsepower outboards. With the new design comes a no-battery-required Electronic Fuel Injection as well as electric and manual start on all models. The new 25hp High Thrust model comes in both 20 and 25 inch shaft lengths for a wider range of applications. Also included, Variable Trolling RPM Switch (VTS®) which allows slower trolling than standard in-gear idle for better fishing.
