Technical FAQ

Can I reuse this gasket after removing it?

How do I know this is the right gasket for my engine?
Cross-reference your engine model and serial number in the Volvo Penta parts catalog. Gaskets are listed by location and serial number range the same engine family can use different gaskets depending on production date and configuration.

Parts Desk Insights

Best use case: This gasket is the right choice when your Volvo Penta service manual or parts lookup specifically calls for part number 1545779. Its most commonly needed during engine disassembly, cover removal, or any service that breaks a sealed joint. Ordering the OEM gasket before starting the job avoids delays waiting for parts mid-service.

Common customer questions: Customers frequently ask if an aftermarket gasket will work in many cases it will, but OEM gaskets are cut to exact tolerances and material specifications for the application. The other common issue is ordering by engine model alone without checking the serial number range, which can result in receiving the wrong gasket for a mid-production change.
