Troubleshooting & FAQ
How do I know if this gasket fits my sterndrive?
This gasket fits a wide range of Volvo Penta, Johnson/Evinrude, and OMC drives. The best way to confirm is to match the part number (3852317) with your service manual's requirements. Also, check the compatibility tables on this page against your specific drive model (e.g., SX-A, DP-SM).
What are the signs of a failed upper gear housing gasket?
Common signs include milky or water-contaminated gear lube, a visible oil leak around the top cover of the upper gear housing, or a low gear lube level without an obvious external leak source. Any of these symptoms warrant an inspection.
Can I reuse the old gasket?
No. Gaskets are single-use components designed to crush and create a seal. Reusing an old gasket will almost certainly lead to leaks and potential damage to the sterndrive from water intrusion or lubricant loss.
What is the recommended replacement interval?
This gasket should be replaced any time the upper gear housing top cover is removed for service, inspection, or repair. There is no fixed time-based interval; replacement is determined by service needs.
Does this gasket require any sealant during installation?
Generally, this type of gasket is designed to be installed dry. Applying sealant can sometimes interfere with proper sealing unless explicitly required by your specific service manual. Always clean both mating surfaces thoroughly before installation.
Is this the correct gasket for my specific engine model year?
While this part fits many models, year ranges are not always available. Please verify the part number 3852317 is correct for your unit by checking your service manual or contacting a qualified marine mechanic. Do not rely solely on the model name.

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.
