We do our best to provide you with the best engine we possibly can. That's why we have taken the 15 hp model and made it better! You can enjoy added features such as a larger displacement, from 328cc to 351cc, and enhanced motor mounts from this durable 15 hp 4-stroke engine. Go ahead; put the engine to the test!
