1984 50hp mariner. i had to remove the shift and throttle cables from the
motor.the remote was in forward gear when i did this.i removed the motor
from the boat and reinstalled it.i hooked cables back and they are not
reversed but i cannot shift out forward.i tried to shift the motor in the up
position and down position both. any body have any ideas?

Lets start he
OK, assuming you are using a correct control box & cables. Disconnect both
cables. Put the engine in neutral by moving the shift slide mech the roughly
its center position. Verify that the engine is in neutral by the ability of the
prop to turn freely in both directions. With the control in neutral, Locate the
shift cable. It will be the first cable to move when you move the lever, (the
shorter of the two when you hold them up with the barrels aligned) Attach it to
the shift mech and adjust the cable barrel adjuster to go in its place.
Let us know how it works out.
