Function

Engine mounts perform several important roles:

• Support the engine weight at the rear of the block

• Absorb vibration from engine operation

• Maintain proper engine-to-drive alignment

• Prevent drivetrain stress on the coupler and input shaft

Worn mounts can lead to:

• Excess vibration

• Engine misalignment

• Premature wear of the gimbal bearing or coupler.

Fitment Tip:
Always confirm compatibility using the engine serial number and sterndrive model (Alpha vs Bravo), as mount designs vary slightly between engine generations.
