I removed the seal about an hour ago. Didn’t have a fancy OMC puller,
and my futile attempts of prying it out were getting me nowhere.
I could not drill a hole in the seal as my drill was too “fat” to
get the right angle. Therefore, I spent about 15 minutes and pulled
the front of the crankcase off.
After seeing the seal area on the crankshaft, I see why the seal
was blowing air on my test. It’s all pitted beyond hope.
Not sure if there’s a “speedy seal” cure for this, but I doubt it.
The pitted area can’t be ground out as the point lobe above the seal area on the
crankshaft is almost the same diameter.
Also, with the seal out, I got a proper measurement on the shaft size
in the seal area.
I measure 1.197 shaft. Specs online for the 308500 seal say
shaft size 1.110 which is a little confusing to say the least.I will ponder my situation and listen to any suggestions, but I’m
not looking to throw a bunch of money into this motor that I
really didn’t want anyway, lol.

There was no Speedi Sleeve option for this crankshaft. I attempted to contact
a person on EBay twice regarding his $45 crankshaft, if the seal area was
“okay” or pitted like mine. No Reply.
Therefore, just so I could at least hear this motor run a time or two, I made
my own “not so speedy” sleeve on the lathe. It’s made out of brass
and about .027 inch thick. I ordered two, non original seals to fit this
sleeve. The seals OD were smaller than needed, therefore I had to make
another sleeve for the seal OD, about the same thickness as the shaft sleeve.
This sleeve I made out of some PVC pipe that was handy.
Do you think it will run long enough just to see if the rest of the power head is
“viable”? If it does, then maybe it’s worth finding a good crankshaft for.
Should I put the two seals with lips opposing?
