Check the oil in the lower unit. If you have a bad seal and it is letting water in it will start bindiing up and your engine will not rev up when it is in gear. If oil is milky looking, drain it and check for metal filings.

That is a long shot, but it won't take long or cost much and needs doing anyway.
