It is molded in white rubber compound and installs in the outboard's water pump housing to circulate raw water through the engine's cooling system, a wear part that should be checked and replaced on a regular service interval to prevent overheating.\u003c\/p\u003e\u003cp\u003eThis impeller is fit-specific to certain Evinrude\/Johnson outboard horsepower ratings and model years, so buyers should confirm their engine's HP and year against the fitment listed here before ordering.
