The biggest challenge of maintaining, fixing or rebuilding a boat engine is sometimes finding the correct parts. We provide easy access to the Yamaha outboard engine diagram catalog so you can diagnose problems and see which replacement parts are required. Click here to go to the official Yamaha outboard motor parts finder page, then enter your boat’s year and model code or the hull identification number (HIN). You’ll instantly see dozens of Yamaha outboard drawings identifying the various parts. After figuring out what part numbers you need, visit our main Yamaha Outboard Motor Parts page or use the search bar to find them.

If you’re having trouble determining the correct parts, don’t understand the diagrams or have other questions, contact Marine Parts Source Monday through Friday. Our staff has extensive technical knowledge of the parts we sell to help with your project. We also offer online resources such as our video on How to Identify Yamaha Engines.
