63P-45987-00-00 Yamaha Spacer 115HP | Genuine Used Part

🔧 Product Description

Genuine Yamaha Propeller Forward Thrust Washer - Part Number: 63P-45987-00-00

A genuine used Yamaha propeller forward thrust washer for selected 115HP to 200HP outboards.

The tapered washer sits on the propeller shaft ahead of the propeller hub. It locates the propeller correctly and transfers forward thrust into the gearcase bearing system rather than allowing the propeller to contact the housing.
