Have you had the lower unit off lately? Also, is the shifter in the tiller handle? Reason I ask this is theres a washer thats on the shift shaft that needs to be in place or it will cause what you are talking about.

This happens on rare occasion if there's water in the gearcase and it freezes, but I see it once every few springs or so. Water freezes inside and forces the guts out the back 1/4". The shifter won't reach the reverse gear. Otherwise everything can work just fine. I doubt that's the case considering your location, but maybe? Easy enough to check. Push the prop forward. If it moves more than 1/8"...

yes, it shifts with the tiller handle, but I unhooked everything that makes it shift with the handle and tried to move shifter by hand and it still wont shift.
