Dear repair guru.. I have a problem with the shifting of my 7.5 merc. I took the lower unit off to change the impeller and put it back to gether as it came out (drive in neutral and prop in neutral). when I put it back in, I can't get the prop to come out of gear when I put in back into neutral or shift it into reverse. Suggestions? HELP Please. I do have the manual but it's not been able to address this issue.. Thanks..
