Impeller Help

Can anyone help me find the unusual impeller style and part number I use on my 1975 Skier with the 225 OMC engine option? I have replaced it before BUT I had the water pump itself off and in my hand and could read some numbers on in. It is a large starfish looking deal and the only numbers I can read are the last few which are __37651 stamped on the back. I guess I could take it off again and do the research but I was just sitting around looking for something to do and thought I would order me a new one. Replaced the last one about 5 years ago. A parts list or schematic would be helpful.

Any help would be appreciated, I can always just go take the pump off and go from there.

Give Billy at mycorrectcraftparts.com a call. He seems to be the resident expert on the OMCs, probably quote ya toe part # off the top of his head...
