Propelling a Revolution

The Yamaha 4-stroke engine is, quite simply, a revolution.

The F225 combines the 4-stroke's clean, quiet, fuel-efficient attributes with the unmitigated muscle of a V6. It's exceedingly lightweight, compact, and smooth-running, and was specifically engineered to meet the demands of today's torque-hungry V6-powered boats. The 24-valve double overhead cam delivers 225 high-end horses, yet it's remarkably stingy with your fuel. Yamaha's unique labyrinth exhaust design makes it so quiet at idling and trolling speeds that you might forget it's running. And it burns so clean that it exceeds emission standards and carries a CARB three-star rating for ultra low emissions. A lean, mean, clean machine.

Standard Features

 In-Bank Exhaust  
    Another Yamaha first. We reversed the conventional four stroke configuration, allowing space for the exhaust to exit between the V-block downward, for a more compact design.  
 Long tube intake tracks are precision tuned to maximize air velocity for added low-end and midrange torque.  
 Inside-track fuel injection positions individual fuel injectors on the inward side of each intake track, saving space and keeping electrical wiring away from the cowling latches.  
 The 24-valve double overhead cam uses 4 valves per cylinder for maximum power, fuel efficiency and reliability.  
 Ram charged manifold fuel injection is another Yamaha exclusive. Each cylinder is fed by its own individual intake track, consisting of a tuned-length passage, a compact throttle valve and a fuel injector. Pulsating pressure "rams" the air / fuel mixture into each cylinder, significantly increasing power and fuel efficiency.
