Description
The coupler shaft is a critical drivetrain component that directly transfers engine power to your Yamaha PWC’s jet pump. A worn or damaged coupler shaft compromises acceleration, creates vibration, and can lead to catastrophic drivetrain failure. This OEM WSM replacement restores factory performance and reliability without the need for machine work or custom fabrication.
Designed as a direct replacement for Yamaha personal watercraft, the 003-251 coupler shaft ensures precise fitment and maintains the original engineering tolerances your PWC was built to. Installation is straightforward for experienced technicians or PWC service centers.
