Engine Compatibility

Commonly associated with large Volvo Penta diesel engine seawater cooling applications. Fitment should be confirmed by exact engine model, serial number, and parts diagram before ordering.

Serial Number Fitment Notice

This pump is not universal. Confirm the Volvo Penta engine serial number, pump size, mounting arrangement, belt/pulley setup, hose routing, and diagram location before ordering. Similar 2-inch pumps can differ by housing, drive, port orientation, and installation hardware.

When This Part Needs Replacement

Replace the seawater pump if it leaks, loses prime, has reduced raw-water flow, overheats the engine, has shaft play, bearing noise, seal failure, corrosion, cracked housing, worn ports, or impeller-related damage inside the pump body.

Installation Notes

Install according to the Volvo Penta service procedure for the specific engine. Inspect the impeller, cam, cover plate, seals, pulley alignment, hoses, clamps, and related hardware during service. After installation, verify strong raw-water flow and check all connections for leaks.
