View OEM CouplerWhat This Engine Coupler Does
The engine coupler connects the engine flywheel assembly to the Bravo sterndrive input shaft, transferring engine power into the drive system.
A damaged or worn coupler may cause:
- Loss of propulsion
- Slipping under load
- Drive engagement issues
- Spline wear or stripping
- Abnormal vibration or noise
Proper engine alignment is critical during installation. Incorrect alignment is one of the leading causes of premature coupler failure.
