Description
The WSM Rubber Drive Coupler Damper for Yamaha 1800 (All) is the rubber damper insert that sits between the drive coupler halves in the PWC driveline. It is not the metal coupler itself. The damper is designed to absorb shock loads during throttle hits and reduce vibration so the engine can transfer power to the pump smoothly.
When the rubber gets compressed cracked or oil soaked you may notice clunking at engagement increased vibration or inconsistent hookup under load. Replacing the damper during service helps protect splines and reduces stress on related components.
What it does: cushions driveline shock helps keep coupler engagement smooth and can reduce wear on the crank and pump shaft splines over time.
- Replacement rubber drive coupler damper insert
