One thing I don't understand is why the engine would not start, unless the drive shaft was locked up. If you have a SX drive the shifting is in the upper unit and if in neutral the boat would have started. A Mercruiser shifts in the lower unit so I guess it could have locked up the drive.
Yes, so the upper unit gears seized up. Further proof that the marina did not put any oil back in the drive. It's virtually impossible for all the oil to go out the prop shaft seal and get replaced by water in just minutes.
I hope to hear a follow-up from the OP. He has only made 2 posts so far.
