Good To Know

Q: Does this come with the bearing already installed? A: Yes, this is a complete bearing housing assembly, so the bearing is fitted in the housing and ready to install on the driveshaft. Q: Will this fit every GP 1800 built from 2017 to 2018? A: It is listed for the 2017-2018 GP 1800, but Yamaha can change driveline parts mid-production, so verify your model and serial number before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
