Why Raw Water Impeller Maintenance Matters

The raw water pump impeller is a critical maintenance item in a marine engine's cooling system. Its flexible neoprene vanes draw cooling water through the raw water system to help maintain proper engine operating temperature.

As an impeller ages, the vanes can become stiff, cracked, worn or damaged. Broken or deteriorated vanes can reduce raw water flow and potentially contribute to engine overheating or cooling-system problems.

Regular inspection and replacement of the raw water impeller can help prevent an unexpected cooling-system failure and keep your inboard marine engine operating properly.

Fitment Note

Always verify your engine model, raw water pump and existing impeller before ordering. Marine engine configurations can vary by manufacturer and model year.
