Fitment references vary by catalog source, so the safest match is always by exact engine model and serial number.
Serial Number Fitment Notice
Volvo Penta D12 cooling parts can vary by engine version, production range, and installed pump configuration. Before ordering, confirm fitment using your engine serial number, existing pump part number, and Volvo Penta parts diagram. This is especially important if the vessel has had a prior pump, gear, flange, or cooling-system update.
When This Part Needs Replacement
Replace the seawater pump if the engine is overheating, raw-water flow is weak, the pump body is leaking, the shaft or bearings show wear, or the impeller/cam area has damage that cannot be corrected with a service kit. Pump replacement is also recommended when repeated impeller failures or seal leaks point to internal pump wear.
Installation Notes
Inspect the mounting surface, related O-rings, gasket surfaces, hose connections, gear drive components, and seawater plumbing before installation. Always verify whether the existing gear, fittings, and related hardware transfer over or need replacement separately, since component diagrams show the pump and related parts as individual items rather than one bundled assembly.

Parts Desk Insight
The important detail with this pump is matching the complete engine setup, not just the D12 family name. A pump may look similar on the bench, but gear, flange, hose connection, and serial-range differences can make the wrong pump an expensive mistake.
