Engine Compatibility
Commonly associated with selected Volvo Penta sterndrive applications including SX and DP-S references. Additional supportable listings also connect this part with DP-SM and selected SX-C / SX-M family references, but fitment can still vary by drive model and production range.
Serial Number Fitment Notice
Fitment may vary by drive model, sterndrive version, and production break. Always confirm compatibility by drive model and serial number before ordering. Volvo Penta directs users to identify the exact engine, shield, or drive when locating the correct spare part.
When This Part Needs Replacement
Replace this bellows when the original component is cracked, split, hardened, leaking, loose, or no longer providing a dependable sealed connection in the exhaust passage. Bellows service is especially important when visible deterioration appears during sterndrive inspection or service.
Installation Notes
Confirm the exact sterndrive application before installation and compare the new bellows to the original part during service. Inspect adjacent sealing areas, mounting grooves, and related hardware so the replacement is installed into a clean, properly supported assembly. Some current listings also note that the genuine bellows may be supplied without clips, so related hardware should be checked before service begins.
Alternate/Superseded Part Numbers
Current references identify this item as 3850426. Related replacement-reference listings also connect this part to 0767724 in interchange-style catalogs, but exact interchange should still be verified by application.
Parts Desk Insight
