Hi. Got a boat from my brother in law. 1992 with a 5.7L Mercruiser and Alpha 1 drive. Great shape and runs great. Shifts great also but when I try to give it more throttle in reverse the cutout switch moves up and it stalls out. He reluctantly told me that he once removed the drive in reverse. The shift "rods" in the bell housing and lower unit don't appear to be bent and move freely by hand. I have replaced all the boots and put in a new shift cable kit but am still having the same problem. Could the remote shift cable have been affected? Thanks, Gary
