Not sure if I am in the correct forum for this question but here it goes. I have a 1982 Johnson Twin cylinder 60hp outboard. I just replaced the lower unit on this motor. I was told my replacement unit was off a 1976 55hp Johnson it has the larger gear case 4 1/8". This unit came with no prop so i bought a used 14 x 13 prop for it, My old prop would not fit because my old lower unit was a standard size. Now after a few days of getting the motor running and mounting the new lower unit i load up the wife and kids and we go to the lake to test her out. Get the boat in the water put the controller in reverse to pull out of the launch and the boat goes....... FORWARD!!!!! put in in forward and it goes in reverse. now first thing i thought was i have the wrong rotation prop. So after tooling around at a top speed of 7mph in reverse but going forward we load up the boat and head for home. I have compared the new prop to my old prop and they are the same rotation so thats not my problem. I am thinking it might be something in my lower unit causing it to rotate the wrong way I do not know much about this other lower unit just what i was told it came off off and that is a commercial grade. would a left rotation prop be what i need or is there some way i hooked up something wrong?
