I have a 1975 65hp mercury 650. I changed the water pump when i put the lower unit back on i can get neutral and forward but no revese. But with the lower unit off i can turn the shift rod and have all 3. Can someone give me some advice on what i can try its starting to get frustrating. Thanks

The shifting spline coming out of the top front of the LU has to be twisted to select the gear that corresponds to where the remote control is positioned. I like N as N is easy to locate on the control and it is the center detent in the lower unit shift pattern. Drop the LU back down, position as I said and put it back up. Some folks use F gear as you can use the prop to turn the drive shaft to mate with the powerhead, but being in N and turning the flywheel will accomplish the same thing.
