- Carefully remove the old plate gasket, ensuring the mating surfaces are completely clean of any old material or sealant.
- Position the new gasket onto the clean, dry surface of the lower unit.
- Reinstall the water pump plate, housing, and impeller. Torque bolts to manufacturer specifications.
- Reattach the lower unit to the engine, ensuring all connections are secure.
- Once assembled, use a water source (flushing muffs) to test for leaks and verify proper water pump operation (check for a steady stream from the tell-tale).
Troubleshooting & FAQ
How do I confirm this gasket fits my specific Mercury outboard?
The best way is to match your engine's model, horsepower, and year to the compatibility table. For absolute certainty, cross-reference the OEM part number (27-19202001) with your service manual or existing part. Pay close attention to serial number ranges in the notes column.
What are the signs of a failing water pump plate gasket?
Common symptoms include the engine overheating at idle or low speeds, a weak or intermittent water stream from the "tell-tale" outlet, or visible water leaks around the lower unit's seams after operation.
Is this gasket compatible with both 2-stroke and 4-stroke engines?
Yes, this gasket is designed for both 2-stroke and 4-stroke models within the 6 HP to 15 HP range, as specified in the detailed compatibility list.
When should I replace the water pump gasket?
It is best practice to replace the water pump gaskets, including the plate gasket, whenever you service the water pump impeller (typically every 1-2 years or 100-200 hours). You should also replace it immediately if you notice any signs of a leak or damage.
