Serial Number Fitment Notice

Confirm fitment by engine model, serial number, pump body, port orientation, and cooling-system diagram before ordering. D5/D7 seawater pumps can share similar layouts, but internal service parts, shaft kits, and impeller references can vary by pump version.

When This Part Needs Replacement

Replace the seawater pump if raw-water flow is weak, the engine overheats, the pump leaks, the shaft has play, bearings are noisy, the housing is cracked or corroded, seals fail, or the pump body is worn from impeller or cam damage.

Installation Notes

Install according to the Volvo Penta service procedure for the exact D5/D7 engine. Inspect the impeller, cam, cap, gasket, wear washer, shaft kit, seals, bearings, lock ring, and cover screws during service. After installation, verify strong raw-water discharge and check all hose connections for leaks.
