Q: How do I know if this gimbal bearing seal will fit my sterndrive?
A: This seal fits a wide range of Volvo Penta (SX-C, SX-M, SX-R, SX-S, DP-SM) and OMC Cobra (1986-1993) models. Please check the "Compatible Engine Models" table and cross-reference your OEM part number (3852548 or 911795) to ensure a perfect match.
Q: What are the signs of a failing gimbal bearing oil seal?
A: The most common sign is water intrusion into the gimbal bearing area, which can lead to a rumbling or grinding noise from the bearing itself. You may also notice grease leaking out from behind the sterndrive or water in your bellows.
Q: How often should the gimbal bearing seal be replaced?
A: It is highly recommended to inspect the seal whenever the sterndrive is removed for service. Best practice is to replace it along with the gimbal bearing as part of regular preventative maintenance, typically every few seasons depending on use.
