Re: Add controls to '72 Johnson 25HP?
Certainly. You will need the two stainless steel locks that attach the cables to the sides of the motor for shift and throttle, and a steering connector that attaches the steering cable to the front carrying handle. That depends on what kind of steering is in the boat. The remote control is called a Simplex control. Or Johnson has the same thing only they call theirs a Ship Master. They are on e-bay all the time. But if you buy a used control, make sure it has the cables included, even if they are no good. The ends of the cables are part of the control and if you don't get the cables you are going to be missing a bunch of parts. You can always replace the cables if they are no good or wrong length. They sell them here at iboats.
