Water Pump Impeller Repair Kit 47-59362T1 18-3087 for MerCruiser Bravo Outboard
Product Overview
Water pump impeller repair kit for MerCruiser Bravo drives, supplied as 1 x impeller with wear plate and O-ring. It replaces MerCruiser 47-59362T1 and Sierra 18-3087. The impeller moves raw water through the drive and engine; a worn one shows up as a weak telltale, overheating at idle, or cracked and set blades when the pump is opened.
