Troubleshooting & FAQ
What sterndrive models does this gasket fit?
This gasket is a direct replacement for Volvo Penta 3860183, specifically designed for the upper housing of Volvo Penta DP-G and DPX-A sterndrive models.
Where exactly is this gasket installed?
It is located between the upper gear housing and its cover, corresponding to position #2 in the official Volvo Penta service schematics for DP-G and DPX-A drives.
What are common signs of a failed upper housing gasket?
