Spent several hours in the boat last night, a/c unit in the door.
Prop shaft had backed out 4 inches on its own.
Got coupling reinstalled.
Shaft key reinstalled.
Pinch bolt sitting in shaft detent.
Pinch bolt tightened hard and wired in place with heavy copper wire.
Shoved the motor back into place, got a few mount bolts into the floor.
Had tried installing 3 new coupling bolts but they were too long.
They went thru the coupling and pressed against the trans housing.
Removed those and went back with original non rusty coupling bolts.
Removed water pump cover to change the impeller.
Had bought 2 paper pump cover gaskets cuz I didn't know which pump I had.
Come to find out neither gasket fit because the pump cover was the type
held on by thumbscrews and has a thin rubber o-ring type seal.
Apparently its an MMI water pump door kit.

So now I have 2 untouched paper water pump gaskets but really need the o-ring type seal.
Guess which is the old part?
Had to gently beat the old impeller copper center ring off the pump shaft.
Shaft in great condition.
All 6 'ears' of the impeller were 1/2 way separated from the base.
Installed new impeller and closed up the back plate of the pump.
Hooked everything up but ran into two issues that I left unfinished.
Having problem lining up the exhaust pipe. Got one bolt and new gasket in. Have to twist the fitting slightly to align the 2nd bolt and hole.
I think the solution to this is to use a rope to pull up the standpipe slightly thus twisting the exhaust pipe just enough for it to align. Appears to be some weight on the pipe causing it to twist.
Also the rear sink side engine mount twisted a bit, so the bolt holes don't align with the holes in the floor.
For this, I can lift the engine slightly with a come-along, realign the mount and drop it back into place.
So other then the exhaust bolt and floor bolts, everything is back together including the new electronic points and coil.
