Hello, I'm Mike.
With boat on trailer and safety tether pulled,shift fwd while turning prop counterclockwise and rev will turning clockwise. If it does not catch both ways trim drive up and inspect where shift cable goes into bell housing and see if the housing as broken away form the brass mount. If this looks ok I would then remove the end of that cable from the shift plate and operate by hand. Pushing cable in for fwd and pulling out for rev. If you are unble to get full gear engagement either way the dive needs to be pulled for complete acle inspection.

Sorry but I beleive it is too dangerous to try and guide you through any on water testing with this problem. Boat will need to be out of the water for these tests or have a mechanic look at it on the water for you.
Only other thing you could try would possibly be the propeller in case of hub failure, but I suspect a problem with the shift cable or gearcase.
Best of luck.
