Description

With a water pump replacement from Boat & RV Accessories, you can keep your boat's engine from overheating.

Though boats are a completely different class of vehicle, boat engines have a lot of similarities with their automotive brothers and sisters. One of the main differences is temperature regulation. If you think an overheated engine is bad news on a highway, experiencing that on a lake, gulf or other large body of water is even worse.

This JMP Marine water replacement pump is a Yanmar replacement for systems that use raw water or seawater for engine cooling. Built with premium materials, it is made to be easily installed and offers long-lasting, reliable service.

This water pump replacement is for use with specific systems. It is part of a large selection of boat replacement parts and components we offer at low prices. Contact our boating experts today to learn more about whether this water pump will help service your model.

Please Note: JPR-YM08IH2 is ONLY for 2GM or 3GM as seen in compatibility list below. This should NOT be confused with 2GMF or 3GMF models. If you have the 2GMF or 3GMF please refer to JPR-YM08IH and its cross-reference information. If still unsure, please contact us or JMP Marine for more information.
