Restore proper cooling flow and protect your engine from overheating with the OEM PCM Raw Water Pump Impeller (Part RP061022). This impeller is built specifically for Pleasurecraft Marine (PCM) 6.0L and 6.2L Monsoon engines that use a serpentine belt-driven raw water pump. It’s a direct-fit service replacement commonly used on Malibu and Axis boats (model years 2015–2019) equipped with these PCM engines. Made from durable neoprene with a double flat-sided shaft, this flexible-blade impeller maintains dependable water circulation through the raw water cooling system. Because impeller blades can wear, crack, or break over time, routine replacement is an essential part of seasonal maintenance and helps prevent costly engine damage.
