Water Pump Maintenance

The water pump is one of the most important components of your outboard's cooling system.

When replacing or servicing the impeller, worn or damaged water pump gaskets should also be replaced to help ensure the pump seals correctly and maintains reliable cooling water flow.

Important – Please Check Compatibility

Please do not order by horsepower or appearance alone.

Mercury and Mariner used different water pumps and gearcases across engines with the same horsepower.

Please check:

Engine model
Engine serial number
Gearbox type
Existing gasket
Original part number

If the gasket looks the same as yours, this does not always mean it is the correct one for your outboard.

If you are unsure, send us your engine serial number before purchasing and our technical team will be happy to check the correct part for you.
