I was cleaning out my Dad’s garage and found a raw water pump and a couple of impellers. It’s the old style pump for the 7.5 kw generators. Onan shows a part number 131-0152 and 131-0182. This is the early style before they switched to the Sherwood pumps. The price is $350.00 with the 2 impellers. The pump is a left over from when we had the Onan repair shop in Freeport, Tx.

Re: NOS Onan Raw Water Pump
Mr Sharp, Jims43dc was just asking where he could get that pump. You have a very fair price on it.

Re: NOS Onan Raw Water Pump
This is the wrong pump, they had two or three different styles, I need the style with the 4 inch pulley, shaft sticks out past the mounting ears by about an inch. Thanks for the post

Re: NOS Onan Raw Water Pump
I was just looking on the trawler forum, there are a couple of members there that have connected 110 volt A/C circulating pumps to their Onans when the raw water pumps like yours failed.

Re: NOS Onan Raw Water Pump
I have thought of doing that but I would still need to have a idler pulley to route the belt over as the same belt turns the captive water pump also. Thinking I will just get piece of SS shaft and turn one out if I can't source one.
