Ok, here is the skinny. I have a 1983 60HP 2 Cyl evinrude(long shaft). I changed the lower unit to a bigger lower unit from a 19?? johnson Lower Unit. They are obviously geared backwards. B/C when I move the throttle forward, it goes into reverse, and vise versa. So to leviate the problem, I installed a hot foot. But, now in reverse, both cylinders fire,and in forward, only the lower fires. I can't even get the boat on plane. Is there something in the throttle control or engine that prevents the upper cyl. from firing with the stick in the "reverse" position????? PLEASE HELP !!!!!!!! :}
