Includes:
- JMP Yanmar Replacement Engine Cooling Pump #JPR-YM08IH
QTY: 1 - Steel Pulley & Mounting Bracket
What is the internal difference between JPR-YM08IH and model JPR-YM08IH2?
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 will give a 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.
- Note:
You can also use JPR-YM08IH for replacement of Yanmar 121575-42000 (replaced by 721575-42702), which is the pump with the NPT threaded nipple port design, but you MUST make sure that you have the rubber hose for inlet and outlet for the JPR-YM08IH hose connections. - Yanmar pump p/n 128990-42500 was replaced by p/n 128990-42510 (Johnson 10-13492-01). The difference is that the original pump 128990-42500 has 17mm Pipe inlet and outlet and 128990-42510 has Pipe inlet (17mm) and pipe outlet (19.5mm). As long as you have the inlet and outlet hose connection setup to accommodate 17mm inlet and outlet then pump JPR-YM08IH will work for you.
