Yamaha High Thrust 25 HP Outboard Motors
Yamaha’s High Thrust 25 HP four strokes are built for jobs that call for more muscle—like pushing a heavy pontoon, adding extra kick to a multi-species boat or maneuvering a sailboat through a crowded marina. Their larger lower units and higher gear ratios produce substantially more thrust than conventional outboards of the same horsepower using standard propellers. In fact, when paired with our Dual Thrust™ propellers, Yamaha High Thrusts produce up to 60 percent more forward thrust and up to 70 percent more thrust in reverse. Now, the T9.9 are also wrapped in powerful style, available in new pearlescent white.
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.
