The raw water pump impeller is one of the most critical maintenance items in your marine engine’s cooling system. The flexible rubber vanes draw cooling water from outside the boat and circulate it through the engine. Regular inspection and replacement at recommended intervals (typically annually or every 200-300 hours) prevents catastrophic engine damage from overheating. Always carry a spare impeller onboard for emergency replacement.
