The ideal solution for raw water marine engine cooling from the originator of the flexible impeller pump. This semi-positive displacement design has superior priming ability, is compact, with simple mechanical characteristics that ensure trouble-free running and long life. The pumps illustrated here are designed and manufactured specifically for engine cooling applications. In addition to these, most of the pedestal mounted pumps can be used for engine cooling. The 17360-1001 is a heavy duty raw water pump that is very similar to the ones found on Detroit Diesel and other large diesel engines. It may be adapted to select engine cooling applications requiring the same size pump by incorporating some minor plumbing specifications.
