- Carefully remove the water hoses connected to the pump inlet and outlet.
- Unbolt the old seawater pump from the crankshaft mounting bracket and remove it.
- Clean the mounting surface on the engine bracket, ensuring it is free of old gasket material and corrosion.
- Position the new pump, aligning it with the mounting holes. Install and tighten the mounting bolts to the manufacturer's recommended torque.
- Reconnect the water hoses to the new pump and secure them with clamps.
- Reinstall the serpentine belt, ensuring it is correctly routed and tensioned.

Troubleshooting & FAQ
How do I confirm this pump fits my Volvo Penta engine?
This pump fits specific V6 and V8 gasoline models (3.0L to 5.7L) manufactured before 2005. The best way to confirm is to match your existing pump's part number to the ones listed in our Part Number Matrix (e.g., 21214599, 3812693). Also, check the Engine & Model Compatibility table and verify your pump uses a crank-mounted serpentine belt pulley.
What are the signs of a failing seawater pump?
Common signs of failure include the engine overheating at idle or low speeds, visible water leaks from the pump's weep holes or housing, a rattling or grinding noise from the pump area, and a damaged or worn-out impeller found during inspection. A cracked housing or reduced water flow from the exhaust are also indicators.
How often should the seawater pump or its impeller be replaced?
As a general maintenance guideline, the impeller inside the pump should be inspected annually and replaced every 1-2 years, or after every 100-200 hours of operation, depending on usage conditions (e.g., sandy or silty water). The entire pump assembly should be replaced if there is a leak, bearing noise, or significant housing corrosion.
Can I replace just the impeller instead of the whole pump?
Yes, impeller replacement is a common maintenance task. However, if the pump housing is scored, the shaft seal is leaking, or the bearings are worn, replacing the entire pump assembly is the most reliable solution to prevent catastrophic failure and ensure long-term performance.
What is the difference between the unpainted OEM and gold aftermarket pump?
The primary difference is cosmetic. Original Genuine Volvo pumps are typically supplied unpainted. Our aftermarket versions feature a gold/brass colored housing made of a comparable marine-grade casting, offering similar performance and corrosion resistance at a better value.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
