Installation Notes

Ensure the engine is off, cool, and the battery is disconnected for safety.
Locate and access the baffle plate on the cylinder block.
Carefully remove the old baffle plate gasket. Thoroughly clean any old gasket material or residue from both mating surfaces to ensure a perfect seal.
Position the new gasket correctly onto the cylinder block.
Reinstall the baffle plate and tighten the fasteners to the manufacturer's recommended torque specifications.
Reconnect the battery, start the engine, and inspect for any exhaust or water leaks around the newly sealed area.

Troubleshooting & FAQ

How do I confirm this gasket fits my specific engine?

This gasket fits certain Mercury/Mariner 50-60HP 3-Cylinder outboards made from 1994 onwards. The most reliable way to confirm fitment is to match your engine's serial number to the ranges listed in the Engine & Model Compatibility table.

What are the signs of a bad baffle plate gasket?

Symptoms of a failing gasket include visible water or exhaust leaks near the baffle plate, engine overheating, an unusual exhaust tone, or a reduction in engine performance.

Can I reuse my old gasket?

No. Gaskets are single-use components that crush to form a seal. Reusing an old or compressed gasket will almost certainly lead to leaks and potential engine damage.

What is the difference between this and the OEM part?

This is an aftermarket part built to meet or exceed OEM specifications in terms of material, fit, and function. It provides a reliable seal at a more accessible price point.

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.
