- Place the new gasket into position. Ensure it aligns perfectly with all bolt holes and passages.
- Reassemble the component, tightening bolts in a star or crisscross pattern to ensure even pressure. Do not overtighten.
- Once reassembled, open the seacock, reconnect the battery, and briefly run the engine to check for leaks.
Troubleshooting & FAQ
Will this gasket fit my specific engine model year?
This gasket fits a wide range of Volvo Penta models without specific year limitations noted in documentation. Please use our compatibility table to confirm fitment for your engine model. If your model is listed, the gasket is compatible.
Why is my new gasket leaking?
Leaks after installation are typically caused by one of three issues: uneven tightening, damaged or dirty mounting surfaces, or an incorrect gasket. Ensure mounting surfaces are perfectly clean and flat, and tighten bolts to the manufacturer's recommended torque in a crisscross pattern.
How do I know if my old gasket has failed?
Signs of a failing cooling system gasket include visible water leaks around the pump or component housing, engine overheating, or a loss of coolant/antifreeze with no other obvious source. A visual inspection will often reveal cracks, brittleness, or compression failure in the old gasket material.
What is this gasket made from?
This aftermarket gasket is manufactured using high-quality materials designed to meet or exceed OEM specifications for durability and sealing performance in a marine environment. The exact composition is proprietary but is comparable to the original part.
Can this be used with non-OEM impeller pumps?
Yes, this gasket is often used with aftermarket components, such as Johnson F35 impeller pumps, that are designed as direct replacements for the original Volvo Penta equipment. Always confirm the pump manufacturer specifies compatibility with OEM part number 802551.
When should I replace my cooling system gaskets?
It is best practice to replace gaskets any time a component is removed for service, such as during an impeller change. Proactive replacement can prevent unexpected leaks and engine damage.
