The raw water engine cooling pump is the heart of the marine engine, supplying a continuous flow of raw water to maintain temperatures consistent with the demanding engine performance. Over the years, Sherwood raw water pumps have developed a reputation of excellence in quality; and today are chosen for their performance and dependability by the most prestigious marine engine manufacturers.

Sherwood pumps are one of the largest suppliers of flexible rubber impeller cooling pumps for marine engines in the USA. Sherwood pumps can be found fitted on some of the most well known engine brands in both pleasure and commercial boats.

To ensure that your boat engine cooling pump performs as required, regular preventative maintenance and inspection should be carried out. The Sherwood engine cooling pump impeller should be replaced every 3 - 12 months depending on application.

The number one reason for premature engine wear is overheating. To maintain engine performance, insist upon genuine Sherwood impeller pumps, impellers and service kits.
