Troubleshooting & FAQ
What are the signs of a failing powerhead base gasket?
Common symptoms include water contaminating the engine oil (giving it a milky appearance), visible exhaust or water leaks from the seam between the powerhead and midsection, engine overheating, or a general loss of performance.
Should I use sealant with this gasket?
This gasket is designed for a dry-fit installation. Applying additional sealants can interfere with proper seating and may not be recommended by the engine manufacturer. Always consult your service manual for the final word on sealants.
My OMC/Bombardier engine isn't listed by model. How do I confirm fit?
This part directly cross-references to OMC/Bombardier part number 5037205. If your engine's service manual or original part number matches 5037205, this gasket is the correct replacement for your 90HP, 115HP, or 140HP model.
