1999 250hp Johnson shift problems.

I just installed this motor on my boat and it shifts and throttles fine in forward, but when I shift it into reverse it shifts into gear fine, but it is very hard to give it throttle. What is the cause of this?

Take the shift and throttle cables off of the motor. Start it up on a flusher and then try it. If it works easy you have problems in your control box.
