The PCM RP061017 Impeller Kit is a genuine OEM raw water pump service kit designed for Pleasurecraft Marine (PCM) and Crusader inboard engines equipped with crank-driven V-belt raw water pumps. This kit includes a precision-molded impeller along with sealing components to restore proper cooling system performance and ensure reliable engine operation.
The impeller is responsible for drawing cooling water into the engine and circulating it through the cooling system. Over time, the rubber vanes can wear, harden, or break down, reducing water flow and increasing the risk of overheating. Replacing the impeller at regular intervals helps maintain consistent cooling and protects your engine from costly damage.
This impeller is commonly found on pre-2004 PCM GM-based engines, making it a critical maintenance item for older inboard applications.

💡 Parts Desk Insight
This is one of the most common PCM impellers—but only for older V-belt systems. If your engine has a serpentine belt, this will not fit.
Quick check: multiple V-belts = this impeller 👍
