Description
 

PCM Raw Water Impeller GM 350/454

This impeller for your PCM Marine Engine will keep your boat from overheating by properly circulating water through the block and manifolds. We recommend replacing your engine impeller every 100 hours or annually to ensure that your boat is properly cooled.

 

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 can start a fire.

 

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.

 

PCM replacement part which fits 1986 and older MasterCraft Boats with a PCM 350/454 GM engine as well as most newer PCM engines in Correct Craft Boats.  This impeller will also fit in almost all PCM/GM applications.

 

It is recommended 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 tear away at your impeller, eventually to the point where the raw water pump can't keep up with the heat output of the engine.  This leads to engine overheating which can lead to engine failure.
