Description
The WSM Replacement Drive Couplers for Kawasaki 900/1100 STX-12 (All) is built to restore smooth and reliable power transfer between the engine and jet pump. In a PWC driveline the coupler system absorbs shock when you stab the throttle and keeps spline engagement stable under load.
Worn parts can cause clunking vibration or inconsistent hookup. Replacing these components during service helps protect the crank spline and pump shaft while bringing back crisp engagement.
Fitment: Kawasaki 900/1100 STX-12 (All). Always confirm your exact model and year before ordering.
