[C320-list] Raw water pump

[Ken Geiger]

Here is a good web site; Big Blue Ocean Marine.  Good pictures and specs.


They caution to select the correct pump for your replacement as there are 2 similar designs, one flowing more which they say is not necessarily good.  See links for each type below

  
"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 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."





Ocean has a good price at the moment for these pumps.

We have 3GM30F-YEU on board. The cost of rebuild kit (+amount of time)
vs new pump is not worth it. Besides, new Johnson pump has a higher
output than the older version.

The new part # for Yanmar is: 128397-42500 for this specific engine.

Simple installation, probably 15 min of labor.
