Troubleshooting & FAQ

How do I know if this repair kit fits my D2 series engine?

This kit is specifically designed for the Volvo Penta D2 models listed in the compatibility table. Cross-reference your engine model (e.g., D2-55F, D2-75C) to ensure an exact match.

What are the signs my sea water pump needs rebuilding?

Common indicators include engine temperatures rising above normal, visible water leaks from the pump housing, a cracked or brittle impeller upon inspection, or reduced water flow from the exhaust outlet.

How often should the sea water pump be serviced?

As a general guideline, the impeller should be inspected annually and replaced if any cracks or wear are visible. A full rebuild using a kit is recommended every 2-3 years or 200-300 hours of operation, depending on usage patterns and water conditions (saltwater vs. freshwater).
