40hp force sometimes shifts sometimes not

[badtnt]

I have a 93 40hp force and recently had to replace my lower unit. After that everything ran fine for a little while then when I went to start it started fine when I went to put it in reverse nothing same with forward nothing. Did this a couple of times and then it started working for a lwhile then it would do this intermittenly. Is the problem in the throttle? the cables look fine. Is it the neutral switch? any help would be greatly appreciated.

Thanks

Welcome to iboats.

It may be in the controls, but doubt it.
It is not the neutral switch. It does not effect shifting, it only prevents the motor from STARTING if it is in gear.

Most likely the shift shaft that connects the lower unit to the powerhead.
There is a coupler and jam nut midway down the shaft. Possibly worked loose, or is out of adjustment.


Check back if more help is needed.

Looks like that is the problem. Thanks. But now I can't seem to find neutral. Is there a procedure I should be following. Thanks again.

Yes, hope and pray.

Just kidding.

Put controls into forward.
Put shift rod from lower unit into forward.
Adjust coupler and nut.
Try neutral and reverse.



Or put controls in neutral.
Try to find neutral for the lower unit.
Adjust coupler to that position.

One method or the other. Which ever works for you.
