I blew up my outdrive and bought a used one. I bought a new impeller kit for it and it seems that it is an "R" type instead of my old one is an "MR" type. It is an older unit than what I had. I hired a guy to help me that says he is a boat mechanic (out of work because of the economy) has all the tools and such. Anyways, the problem is every time the unit is put on you either get forward and neutral or reverse and neutral. He has put it on 25 or 30 times so far and it still won?t shift right. I have been helping him and watched and even lined up the shifter myself 5 or 6 times. The problem is ... what I will call the "boot and the foot" if you turn the boot and foot all the way right (clockwise) it goes in reverse, center is neutral, and left is drive. The shifter from the boat when hooked up and the lower unit isn't attached so you can see it, shifts the opposite direction. We laid it side by side with the old one and it moves the same as the other one. Is this "R" type different somehow and won?t work or is there something we are not doing right? And yes it is a standard spin unit. Not left handed. We have a whole day into trying to get this thing mounted and ready to go but for some reason the boat GODS say no. Any input would be of great help.
