SO How bad is it? 1958 AD-12

[pro-crastinator]

Two videos,
The first is on the boat underway, coming back from a morning run. Motor ran like a champ, started immediately and the
"marble in the can" sound started after several hours and 2.5 gallons of gas that took us 20 miles or so. Half the time we were at trolling speed just poking around.

Second video is powerhead on the bench looking at fuel leaking around crank/drive bearing.

Pulled the bottom apart and the gears in the foot are pristine.
Now for the videos -

And , has anybody "seen" Frank lately? or has my schedule been that messed up?

I hear the sound in the first video, don't know what it is. Second video is "private", won't let me look.

check it now. it was slow to get done

Ok, I see what you are concerned about. But it is totally normal. Normally, the carbon seal assembly which is still on your drive shaft stops that blow-by. However, as I watched you rotate it, I saw the magneto plate trying to rotate also. That strongly suggests something is rubbing under the flywheel. Could be the coils rubbing on the magnets, or it could be something loose in there. Whatever it is, may be your noise.

Thanks Frank.
Note that when I got the motor and replaced the impeller, the cork seal (that should seal this spot) was not there.
It is now.
I did pull the flywheel and could not see any rubbing evidence.
Will take more pics this weekend.

That dam* sound sounds like damage being done.
WOuld you run it?

Nope. Might be getting ready to toss a connecting rod through the crankcase. Missing lower seal will do that. (Lets water into the crankcase, destroying the rod bearing).

So it sounds like the next step is to split the case and see whats inside.
