Indmar Water Pump Impeller

This Indmar Water Pump Impeller fits most Indmar marine engines found in (Malibu, Supra, Moomba, etc.) and almost every MasterCraft produced from 1987 until the change to Ilmor engines in 2011.

Your boats raw water pump is designed to use the water it pumps to lubricate its impeller. Do not run the engine unless the boat is in water. If you run the engine with the boat out of the water, the water pump may be damaged, and you will shorten the life of your impeller.

Engine overheating can cause damage to your boats motor and exhaust system. If you operate your boat in shallow, silty or sandy conditions we recommend that you inspect your boats impeller more frequently to ensure your boats cooling system continues to operate correctly.

Indmar recommends that you change your impeller annually or every 100 hours (whatever happens first) and keep a spare in your boat.  Natural wear and debris in lake water shorten the life of your impeller.  This leads to engine overheating which can lead to engine failure.
