Engine Compatibility
The strongest supportable fitment for 3583339 is within Volvo Penta sea-water engine applications tied to the sea-water pump and filter assembly. Current seller references explicitly associate it with models including D4-180I-B, D4-180I-C, D4-180I-D, D4-210A-A, D4-210A-B, D4-225A-B, D4-225A-C, D4-225A-D, D4-225I-B, D4-225I-C, D6-280A-A, D6-280A-B, D6-280A-C, D6-280A-D, D6-280I-A, D6-280I-B, D6-280I-C, D6-280I-D, D6-310A-A, D6-310A-B, D6-310I-A, plus certain 8.1 IPS applications. Because pump and filter hardware can vary by serial break and cooling-system layout, final fitment should still be confirmed against the exact Volvo Penta parts diagram and serial number.
Serial Number Fitment Notice
Match Volvo Penta part number 3583339 to your engine serial number and the correct Volvo Penta sea-water pump and filter diagram before ordering. Cooling-system service parts in this assembly can vary by engine version, drive configuration, and production break, even when the surrounding hardware looks similar.
When This Part Needs Replacement
This pressure plate should be replaced when it shows corrosion, distortion, scoring, sealing-surface wear, or damage during sea-water pump or filter service. It is also smart to inspect it anytime the surrounding strainer, cover, sealing ring, or pump components are already apart, since wear in this section of the raw-water system can lead to repeat labor if reused in poor condition.
Installation Notes
Confirm the exact application in the correct Volvo Penta schematic before installation, and compare the removed part carefully against the replacement pressure plate. Inspect the mating cover, strainer, and sealing ring surfaces before reassembly. In sea-water pump and filter assemblies, exact schematic match matters more than a quick visual comparison.
Alternate/Superseded Part Numbers
Current parts sources continue to list 3583339 as the active Volvo Penta OEM number. One current seller also notes it as part of kit 21400685, and the assembly diagram shows 21400685 as a kit alternative associated with nearby cover-related positions in the same sea-water pump and filter assembly.
Parts Desk Insight
With pump and filter hardware like this, the easy mistake is focusing only on the main pump and overlooking the smaller internal parts that help keep the assembly working correctly. Matching the exact sea-water pump diagram first usually saves time, especially when nearby plates, covers, and strainers in the same assembly can look more interchangeable than they really are.
