Hi

I am hoping someone can help me with the info on two questions. 1) what after market/third party impeller(s) can I use on the 3GM30F? 2) is the raw water pump and coolant pumps both use the same type impellers? Thank you very much!

Though more expensive I prefer using orm parts but that's just my humble opinion. Coolent pump is a metal impeller.

I believe there is a difference between impellers for pumps on "European" and on "Japanese" motors.

That is to say, impellers in the raw water pumps.

Do you know where can I buy NONE original yanmar impeller? Does it have a part #?

First of all there are two different model raw water pumps and so two different raw water pump impellors that were used on the 3gm30F so you need to know the serial number of you engine. (I have one also). One is slightly wider than the other. I am told that the narrow impeller doesn't pump enough water in the wide pump and the wide one burns out in the narrow pump and the pump tends to leak and score the cases.
