Troubleshooting & FAQ

How do I know if this gasket fits my specific Volvo Penta engine?

This gasket replaces OEM part number 827250 and is designed for sea water pump II assemblies on various Volvo Penta stern drive engines. The most reliable method is to verify your engine's required part number and visually compare your old gasket to the product images before ordering.

What are the signs of a failing sea water pump gasket?

Common symptoms include visible water leaks or drips around the sea water pump, engine overheating alarms, steam from the engine compartment, or a noticeable decrease in cooling system efficiency.

Should I use sealant with this gasket?

In most cases, this gasket is designed for a dry installation. However, always consult your specific engine's service manual, as some applications may recommend a light application of a non-hardening sealant.

When should this gasket be replaced?

It is best practice to replace the sea water pump gasket whenever the pump is removed for service, such as during an impeller change. It should also be replaced immediately if any leaks are detected.
