Troubleshooting & FAQ
How do I confirm this pump fits my specific engine?
This pump is designed for Volvo Penta 4.3L, 5.0L, and 5.7L V6/V8 engines (GI, GXI, GL models) that use a crankshaft-mounted pump with a serpentine belt. To ensure compatibility, please verify your original part number matches one of the cross-references: Volvo Penta 21212799, 3812519, or Johnson Pump 10-13569-11 / 10-13569-01.
What are the common signs of a failing raw water pump?
Key symptoms include rising engine temperatures at idle or low speeds, visible water leaks from the pump body or weep hole, reduced water flow from the exhaust, or a high-pitched squealing or grinding noise from the pump bearing while the engine is running.
How often should the impeller be replaced?
The internal rubber impeller is a wear item and should be inspected annually. We recommend replacing it every 1-2 seasons of use, or more frequently if you operate in silty or sandy water conditions, to prevent overheating and engine damage.
Is the impeller included with the pump assembly?
Yes, this pump arrives fully assembled and includes a brand new, pre-installed impeller, making it ready for immediate installation.
Is this an OEM Volvo Penta part?
This listing is an aftermarket replacement (not OEM). It is built to OEM-level specifications with comparable materials and is manufactured in an ISO 9002 facility, with batch-inspections for consistency.
What is the shipping speed & cost?
We ship worldwide quickly—typical transit is 5–15 days. Standard shipping is free; expedited options will appear at checkout where available.
What is the warranty and return policy?
