Volvo Penta 3852548 is a gimbal bearing / transom driveshaft oil seal used in supported Volvo Penta SX and DP-SM transom shield assemblies.

Volvo Penta diagram references show 3852548 as a seal in the transom shield assembly, alongside related components such as O-ring 3852537, rubber collar 3860365, ball bearing 184860, and bellows 21277185 / 3885870.

Engine Compatibility
This seal is primarily transom-shield and drive-family specific rather than engine-displacement specific. Cross-reference fitment data lists it for Volvo Penta SX-C, SX-M, SX-R, SX-S, and DP-SM transom applications, and also for compatible OMC Cobra transom / sterndrive applications where the same seal reference is used.
Serial Number Fitment Notice
Seal fitment depends on the exact Volvo Penta transom shield, drive model, gimbal bearing setup, and serial number range. Always confirm compatibility using the Volvo Penta parts diagram and serial number before ordering, especially when cross-referencing 3852548 with OMC / BRP 911795 or aftermarket equivalents.
When This Part Needs Replacement
Replace this seal during gimbal bearing or transom shield service, or if the original seal is worn, hardened, torn, leaking, corroded, or damaged during removal. A compromised seal can allow water and debris into the gimbal bearing area and may shorten bearing life.
Installation Notes
Install as a direct press-fit seal in the correct transom shield location. Inspect the gimbal bearing, bellows, driveshaft surface, seal bore, O-rings, and surrounding transom components while the area is apart. Confirm the seal is pressed in squarely and fully seated before reassembly.

Parts Desk Insight
This seal is best matched by transom shield and drive model, not by engine size. If the gimbal bearing area is already open, it is smart to inspect the bellows and bearing at the same time because a leaking or aged bellows can damage the new seal and bearing quickly.
