Industrial 47-59362T Water Pump Impeller

Industrial 47-59362T Water Pump Impeller is a direct aftermarket replacement for Mercury/MerCruiser sea-water pump impellers, designed to fit MerCruiser engines that originally used part 47-59362T. In the aftermarket ecosystem, this part is commonly sold as Sierra 18-3087, which is listed as replacing 47-59362T-1 for 1999 and older MerCruiser models, offering a compatible option for rebuilds of older installations. Mercury/MerCruiser also markets the 47-59362T family in service kits such as 47-59362T6, which bundles the impeller with the pump components needed for a full service. As a member of the Quicksilver/Mercury OEM lineup, this impeller is presented by retailers as a genuine replacement part for MerCruiser seawater pumps, intended for use in engines that rely on the 47-59362T series. Typical applications include replacing worn or degraded impellers in MerCruiser raw-water pumps to maintain proper cooling performance, especially in vessels where ocean or lake water is used for cooling. Installations using the 47-59362T family generally require the correct pump body and wear plate compatibility, and the 47-59362T parts have been referenced across multiple supplier catalogs as compatible replacements for older MerCruiser pumps.
