PCM / Crusader RP061022 Raw Water Pump Impeller

The PCM RP061022 Raw Water Pump Impeller is a direct OEM replacement impeller designed for Pleasurecraft Marine (PCM) and Crusader inboard engines equipped with serpentine belt-driven raw water pumps. This impeller is responsible for circulating cooling water through the engine, maintaining proper operating temperature and preventing overheating.

Constructed from marine-grade neoprene rubber, this impeller delivers reliable flexibility, durability, and consistent water flow in both freshwater and saltwater environments. Replacing a worn impeller restores cooling performance and helps protect critical engine components from heat-related damage.

This impeller is commonly used on 2003+ PCM and Crusader engines with serpentine belt systems, making it a key maintenance item for modern inboard applications.
