Troubleshooting & FAQ
How do I know if this gasket fits my engine?
This gasket is designed for select Yamaha 40HP 2-Stroke outboard engines and also cross-references to several Volvo Penta, Mercruiser, and Parsun models. The most reliable way to confirm fitment is to match your existing part number to one of the equivalents listed in our Part Number Matrix.
What are the common signs of a failed cylinder gasket?
Common signs include a noticeable loss of engine compression, engine overheating, white smoke from the exhaust (indicating coolant is burning), milky or discolored oil, and visible oil or coolant leaks from the engine block/head joint.
Can I reuse my old cylinder head bolts?
It is strongly recommended to use new cylinder head bolts when replacing a gasket. Head bolts are often torque-to-yield, meaning they stretch during the initial installation and will not provide the correct clamping force if reused, which can lead to gasket failure.
Is sealant required for gasket installation?
In most applications, this gasket is designed to be installed dry on clean, flat surfaces. Applying sealant can interfere with the seal and cause premature failure. Only use sealant if explicitly required by your engine's service manual.
