78 37C gen set impeller Part #

I have a 1978 37C with an Onan 7.5 diesel Genset.
Jabsco water pump. looking for the impeller part number. Any body have it handy?
Yes I am too lazy to crawl in to find it.

If it's an Onan MDJE 7.5kw, my notes show that the impellor is 131-0386. That # replaced the old part # 131-0218. The repair kit for the pump includes the impellor and is part # 131-0258.

Edit - That's the raw water pump, not the circulating pump.

Thanks for the info it turns out to be exactly what I needed. I have 3 impellors for the circulating pump. Raw water pump was what I needed.

Isn't the circulation pump centrifugal?

They dont take rubber implers.

Yeah, if I recall, the circulating pump had a pair of brass gears, not an impellor.

That's true !!
