12-82560M – Washer – Mercury / MerCruiser

The 12-82560M MerCruiser washer is an OEM Mercury Marine hardware washer used in specific outboard and stern drive assemblies. It usually appears in gear housing and forward thrust washer locations where a flat washer helps secure components and spread load. Many parts catalogs list it as a small but essential gearhousing washer in original Mercury marine diagrams.

Small washers may seem simple, but they play a key role. The 12-82560M MerCruiser washer sits under bolts and nuts to reduce wear on mating surfaces. It also helps prevent paint damage and metal distortion when fasteners tighten. Because marine engines vibrate a lot, using the correct washer helps keep fasteners from loosening. This can improve long-term reliability and reduce the need for frequent checks.
