Volvo Penta 3888837 is a genuine OEM gasket used in Volvo Penta seawater pump and cooling-system service. Current parts references place this gasket in a seawater pump assembly diagram alongside hose attachment 848596, flange 842029, and pipe 21120684, which gives it a strong application trail as the sealing gasket for that exact flange-to-pump connection where 3888837 is specified. Current Volvo Penta parts references also show earlier part number 820877 updating to 3888837.
Key Features
- Genuine Volvo Penta OEM gasket, part number 3888837.
- Listed in current seawater pump assembly references for Volvo Penta applications.
- Appears at the flange and hose-attachment section of the seawater pump diagram, which supports it as a cooling-system sealing gasket.

Engine Compatibility
The strongest supportable fitment for Volvo Penta 3888837 is as a seawater pump or cooling-system flange gasket in the assembly where this exact part number is called out in the Volvo Penta diagram. Because the available public references for this number are stronger on assembly position than on a broad engine-family list, the safest fitment standard is the exact Volvo Penta parts breakdown for the engine being serviced rather than matching by appearance alone.
Serial Number Fitment Notice
Fitment can vary by engine family, pump revision, and serial-number range. Confirm Volvo Penta part number 3888837 against your engine serial number and the correct seawater pump diagram before ordering, especially on engines that may have had prior cooling-system service or updated pump components.
When This Part Needs Replacement
Replace this gasket whenever the seawater pump flange or adjacent cooling-system joint has been opened, or when the original gasket shows seepage, flattening, tearing, swelling, or damage during disassembly. Replacing it during adjacent pump or hose-connection service is usually the safer move than reusing an old compressed seal.
Installation Notes
Install on clean, flat mating surfaces with all old gasket material removed. Confirm the gasket matches the exact flange position in the seawater pump diagram before assembly, and tighten related hardware evenly to help prevent repeat leaks. Matching the gasket together with the neighboring flange and hose-attachment components shown in the diagram is a practical cross-check during service.
Alternate/Superseded Part Numbers
Current Volvo Penta parts references show earlier part number 820877 updating to 3888837. Use 3888837 as the current primary OEM ordering number for this listing.
Parts Desk Insight
With small pump-side gaskets like this, the easy mistake is matching by shape alone after teardown. On Volvo Penta cooling-system service, using the exact seawater pump diagram and serial-number-based lookup usually saves more time than reopening the job for a small leak later.
