Re: 40hp johnson tiller to remote
Yes you can convert it to console steering. You will need a remote kit from I.boats or another omc supplier or your local Evinrude/Johnson dealer can order, approx $90.00 If you have a model no J40teeds, there is not kit for that motor, that's is the problem I am having now. I even talked to the Evinrude/Johnson factory today and they comfirmed that. Good luck with your conversion.
Now I don't know if your shift box will work with that motor or not, you may have to change the shifter also.
