Description
The JPR-YM08IH is a Yanmar replacement engine cooling seawater pump.
Q: What is the internal difference between JPR-YM08IH and model JPR-YM08IH2?
A: The difference is the thickness of the machined "Cam" which is incorporated or part of the Body / Casing itself. The machined thickness of YM08IH is greater (4mm) vs a smaller thickness (2mm) found in the JPR-YM08IH2. So, the JPR-YM08IH model gives higher flow rate vs JPR-YM08IH2. This is why it is very important to order the correct pump for your model of engine by referring to the cross-reference information provided.
