Serial Number Fitment Notice
Always verify by complete drive designation and serial number — not just the boat's engine model. Several similar-looking rings are used within Volvo Penta upper gear and vertical shaft assemblies and may differ by drive version or production range. When in doubt, cross-reference the schematic before ordering.
When This Part Needs Replacement
Replace the ring when inspection reveals any of the following:
- Bent, distorted, cracked, or visibly worn
- Scored or damaged during drive disassembly
- No longer retaining or locating its adjoining component correctly
- Specified for replacement during upper-gear or vertical shaft servicing
Installation Notes
Identify the ring's exact schematic position before removing the original component. Inspect surrounding shaft, bearings, spacers, and retaining components for wear. Related components in the same upper vertical shaft stack include spacer ring 3860273, locking clip 3852295, O-ring 949656, and shaft 3852292. Install according to the Volvo Penta workshop procedure for the applicable drive model.

Parts Desk Insight
This ring is used across several drive families, but that doesn't make every upper shaft assembly identical. The most common ordering mistake is selecting by appearance rather than drive serial number and diagram position — a nearby spacer or retaining ring can look nearly identical. Confirming drive family and schematic location before you order saves a return trip.
