have you tried finding a position while it's in gear and while the neutral pin is pulled (i'd bet in gear vs neutral will be the ticket)? i don't think you'd find one that's totally lined up with the hole. there will still be some finagling involved...pulling the rear of the unit away from the wall while sliding it to the stern.

once you get it...do your best to remember what the trick was since you're have to repeat it in reverse to reinstall.

if you have time to search the trick has been posted before but i can't remember who had it.
