I have a 1985 Mercury 35 hp tiller handle motor on my boat.

Time before last that we went out it performed perfectly.
Then the last time we went out I fired it up and put it in reverse to back it off the trailer and it wouldn't do anything.

Basically it won't go forward or reverse.
The prop spins free but it just won't go in gear.

I THOUGHT there was a pin out of a hole in the engagement "bracket" but I looked today and there is nothing to put in that hole.

The gear shift moves fine but "something" just ain't clicking.

Anyone ever heard of such or had such?
Any input would be greatly appreciated.
