Back from vacation and getting this in motion- once it went down I parked and never really looked at anything. All of you have given good suggestions what to look at but another thing occurred to me and I need to bring it home to be 100%- went it went down and I moved the shifter from forward to reverse, I don't recall that the engine reved? It definitely made the noise I described and it did go "out of gear" because I can turn the prop by hand- would this point to possibly some other event rather than the couplet? I'd say it was just a cable except for the horrible noise it made and I can think of anything in the shift that would have made the noise I heard...
If you can see the shaft between the rear of the engine and the transom (maybe use a small mirror) have someone move the prop with the drive in gear. If the shaft does not turn, it would indicate an issue with the drive or ujoint. Also look for pieces of rubber by the shaft which would indicate a coupler failure. If the shaft turns (obviously the engine will not turn by hand) then it would indicate a coupler failure.
Update- it was the coupler! I do find that a relief although I don't like pulling the motor...anyway, he has given me a price of $1800 bucks to do it, stated the coupler is a little over 800 so that's 800 labor to pull the motor...what do you think of the repair cost?
thanks all for the input, as soon as I can sweep up a couple of boat bucks I will get the work done but have a lot on my plate right now but will consider this closed and will be back on the water as soon as I can. Unless I run into a bunch of other stuff. Only 200 hours on the boat so I don't expect any other issues....
