Confirm fitment by engine model, serial number, pump part number, port orientation, and mounting arrangement before ordering. Similar Volvo Penta seawater pumps can differ by flange style, drive arrangement, impeller, shaft, and installation hardware.
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 engine. Inspect the impeller, cover plate, cam, wear plate, shaft, seals, bearings, flange faces, hoses, and clamps during service. After installation, verify strong raw-water discharge and check all connections for leaks.

Parts Desk Insight
This is a large-engine seawater pump, not a universal utility pump. The strongest match points are 822787 / 3829311 / 846354, 1-1/2" flange ports, and the engine family. Always compare the old pump's port orientation and mounting before installation.
