  1. Disconnect the battery and allow the engine to cool completely. Drain the cooling system.

  4. Place the new gasket onto the engine block, carefully confirming the correct orientation based on dowel pins and passages.

Troubleshooting & FAQ

How do I confirm this gasket fits my specific engine?

This gasket is designed for Volvo Penta MD11C, MD11D, MD17C, and MD17D models. Always cross-reference the part number 859137 with your engine's service manual and visually compare the gasket design with your old part before installation.

What are common symptoms of a blown head gasket?

Signs include engine overheating, white smoke from the exhaust (coolant burning), milky or frothy engine oil (coolant mixing with oil), loss of compression, and poor engine performance. If you notice these, inspect your head gasket immediately.

Should I use sealant with this gasket?

Generally, modern head gaskets like this one are designed to be installed dry without any additional sealants. Applying sealant can interfere with the seal. Always follow the specific instructions in your engine's workshop manual.

How long does a marine head gasket last?

There is no fixed replacement interval. Lifespan depends on engine hours, operating conditions, and proper installation. It should be replaced whenever the cylinder head is removed or if it fails.

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.
