I thought they used a Chicago Rawhide seal. Where there any numbers on it? That is supposed to be a 0.988″ shaft. Look for a seal at a wholesale house with an inside diameter of 25mm. Good Luck

No numbers that I could see . It looks more like 32 mm ID …
I think it may still be usable but definitely getting crumbly around the edges .
It’s flat on the bottom with sort of an upside down V shape on top .
May have been round originally idk …
The ring fits on the shaft coupler resting on the impeller and seals in the beveled upper housing . So it’s either spinning with the shaft or it’s sticking to upper housing and shaft spinning inside the ring .. So thinking an o ring more this style idk ..https://www.mcmaster.com/o-rings
Basically just needs to be beveled on the outside I guess . Shaft mounted rotary seal 9562K47
Sorry – I was looking at the wrong part. The water intake on those models was larger than the water tube. At speed more water was forced in than the output could handle. The water would fill the driveshaft housing and rust the crank shaft.That seal was the first attempt to stop that. some were cork. some were leather. Later holes were drilled to let the water out of the housing, which solved the problem. It was common for racers to remove that seal, shave down the water pump and drill extra holes in the driveshaft housing to gain a little more horse power. A small “O” ring will do – it’s not that important.
