Removed lower unit with remote control in Neutral.When replacing lower unit i put remote in forward and LU in forward.when turning prop clockwise the shaft turns as it should but if I turn prop CC the shaft should turn freely but it also turns shaft CC with remote in forward.I have tried LU gear positions in all positions but get the same results.Suggestions to remedy this problem please.Thank you.
When the gear box ix in forward, it should make a ratcheting noise when rotated forward and should not turn at all when turning in reverse (or be resistant as your back spinning the water pump -don't do that) Once in gear (forward ) you should be able to mate the shift to the motor. I have removed the prop and nut and used a remote start to spin every thing together, but requires a lot of safety precautions.
If you are working on an older mercury, that shift rod can work both ways with disastrous results if you over spin the shifter to the back side of the detent.

sound like the shift fork, or fwd gear is damaged in the lower unit.....special tools are required for this repair .....if you got them cool, if not seek a shop for further assistance.......hope this helped...GL

I would think that the problem is a worn clutch dog. Drain the gear oil from lower unit. You need to disconnect the shift linkage and pull the lower unit like you would to change the water pump. Then remove waterpump housing and waterpump base. The base will have a seal so you need to be careful and gently and evenly pry the base up until it comes off. Next you need to remove the prop and depending on the year there is a ring screw around the prop shaft that needs removed. Also there is a phillips screw that needs to be removed near the lower gear oil drain plug. That screw holds the shift cradle in place. From here you should be able to slide the drive shaft up and out and the prop shaft should slide out. The clutch dog is the smaller piece in between the two gears that engages fwd and rev. You really should have a mechanic do the work but if you get a book it will help you. Pay very close attention how it comes apart and make sure that you dont mix up the fwd gear with the rev. gear.

Start by adjusting your idle mixture screw. Start at 1 1/2 turns out and with the engine in gear at an idle slowly turn the screw clockwise until the engine starts to die, then back off a half turn and that will be your proper setting. If you need to you can bump up your idle stop screw just a touch so it will hold also.

You may have spun the hub inside your propeller. Look between the center hub with the splines and the casting of the prop there is a rubber insert in there. See if it is distorted. The nut and washer are keeping the prop on but I think you will find if you put it in gear and try to turn the prop by hand it will spin and the shaft will not move.

if you haven't fixed this already, take the pastic water pick up covers off there are two joiner nuts in there undo them, there is a plastic cone on each end take them off and it will slip through. I own the same model and year outboard.
