Volvo Penta Gasket Kit 3812357

Volvo Penta 3812357 is a genuine OEM gasket kit used in Volvo Penta IPS drive service. Current parts references identify it specifically as a lower gasket kit, and the strongest public application trail places it in IPS-A miscellaneous repair kits and IPS gearcase component references. That makes it a strong match for lower-unit sealing service where this exact Volvo Penta number is called for.

Engine Compatibility

The strongest supportable public fitment trail for Volvo Penta 3812357 is with Volvo Penta IPS drive applications, especially the lower gearcase / lower sealing service group. Current public references consistently associate this kit with IPS-A through IPS-F families, but the safest fitment standard remains the exact Volvo Penta parts diagram and drive serial number for the IPS unit being serviced.

Serial Number Fitment Notice

Fitment can vary by IPS generation, lower housing revision, and serial-number range. Confirm Volvo Penta part number 3812357 against the exact drive serial number and the correct lower-unit parts breakdown before ordering, especially on IPS systems that may already have had previous seal, retainer, or lower-gearcase service.

When This Part Needs Replacement

Replace this kit whenever the related IPS lower-unit sealing area has been opened, or when the original gaskets, sealing rings, or O-rings show leakage, flattening, hardening, or damage during teardown. Because this is a grouped sealing kit rather than a single gasket, replacing the service components together is often the cleaner way to avoid repeat labor on the same lower-unit repair.

Installation Notes

Install only on clean, undamaged mating surfaces and verify the kit matches the exact lower-unit service point before assembly. Current public references support this as a lower IPS sealing kit with multiple included seals and gaskets, so matching the exact drive family and service diagram first is the best cross-check before disassembly or reassembly.

Alternate/Superseded Part Numbers

Use Volvo Penta 3812357 as the primary ordering number. Current public references reviewed consistently present this number as the active OEM gasket-kit identifier for the lower IPS service group.

Parts Desk Insight

With IPS lower-unit service, the costly part is usually reopening the drive, not the sealing pieces themselves. Matching the exact serial-number-based IPS breakdown first is usually the easiest way to avoid a small leak turning into a second repair.
