2022 Yamaha 8HP Portable Motor – YM597 This Yamaha 8HP four stroke motor has an added resting pad which means more storage options and improved storage stability, while the redesigned tiller handle allows the stored motor to take up less space. The driveshaft on the new F8 has a special centre section that is narrower than the ends. It is designed to temporarily "twist" should the prop coming into hard contact with an underwater object, protecting the powerhead, propshaft and other vital engine components. The shortened tiller handle is now easier to use than ever before. Its new shift level shape provides better grip for precise shifting. * While every reasonable effort is made to ensure the accuracy of this information, we are not responsible for any errors or omissions contained on these pages.
