Troubleshooting & FAQ
How do I know if this kit fits my pump?
This kit fits Volvo Penta engines from 1999–2005 (3.0L to 8.1L) with a crankshaft-mounted raw water pump. Verify your pump matches the part numbers 21214595, 21214596, 21214599, or 21214601. Visually comparing your old parts to our product images is also recommended.
What are the signs my raw water pump needs a rebuild?
Common signs include water leaks from the pump body (especially from the weep hole), engine overheating at idle or low speeds, a decrease in water flow from the exhaust, and a visibly worn, cracked, or deformed impeller.
How often should the pump be serviced?
Impeller life varies based on usage, water conditions (sandy/silty water causes faster wear), and winterization procedures. It is best practice to inspect the impeller annually and replace it every 1-2 years as preventive maintenance, even if it looks okay.
Is this kit difficult to install?
Installation requires moderate mechanical skills. While replacing the impeller is straightforward, removing and pressing in the new bearing and seals can be challenging without the correct tools (like a bearing press or puller). Professional installation is recommended if you are not experienced with these tasks.
My engine is still overheating after installing the kit. What's next?
If overheating persists, verify the impeller was installed with vanes pointing in the correct rotational direction. Check for blockages in the intake hose, heat exchanger, or exhaust manifolds. Ensure there are no air leaks on the suction side of the pump.
