90501-10227 – COMPRESSION SPRING – Yamaha

The 90501-10227 Yamaha spring is a genuine OEM compression spring used in Yamaha outboard starter assemblies. It provides controlled spring tension that helps key components return or hold position during engine starting and operation. This compression spring is listed in factory diagrams for starter assemblies on many older Yamaha outboards.

This spring carries out an important mechanical function. It compresses when engine parts move, stores energy, and then releases that energy to support consistent motion and return of starter parts. When the 90501-10227 Yamaha spring weakens, you may notice inconsistent starter action or parts that don't reset properly. If the compression drops, the spring may not return starter linkages or pawls fully, which can make the starter feel sticky or sluggish. That is why replacing worn springs matters for reliable starting and smoother operation.
