Johnson Raw Water Impeller Gasket

This Johnson Raw Water Impeller Gasket fits almost all Indmar marine engines (Malibu, Supra, Moomba, etc.) and almost every MasterCraft produced from 1987 until the change to Ilmor engines in 2011. This foam gasket should be replaced everytime you take your impeller gasket cover off. Don't let a inexpensive foam gasket be the troubles of your boat over heating and not getting enough water. 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.

Use the boat part look up below to ensure you are purchasing the correct part for your boat.
