Troubleshooting & FAQ

Q: How do I know if this seal fits my sterndrive?

A: This seal is designed for Volvo Penta SX, DP-S, SX-A, and DPS-A drives, as well as various OMC Cobra models. The best way to confirm fitment is to match one of the direct replacement part numbers (Volvo Penta 3852548, OMC 911795, Sierra 18-8349, or Quicksilver 86300) with the part number listed in your engine's service manual.

Q: What are the signs of a failed gimbal bearing seal?

A: The most common signs of a failed seal are water found inside the drive bellows or a growling/grinding noise coming from the gimbal bearing area when turning the wheel. A faulty seal allows water to wash the grease out of the bearing, leading to premature failure.

Q: How often should the gimbal bearing seal be replaced?

A: It is highly recommended to replace the gimbal bearing seal anytime the sterndrive is removed for service. It should always be replaced along with the gimbal bearing as part of routine maintenance to prevent water intrusion.
