I recently bought a little project boat with a blown1990 Force 90hp. I've been searching hard for another motor to replace it on somewhat of a budget. I've found a very clean '84 Johnson with low hours at a good price. My question is this...the boat I am putting the motor on obviously has the controls for the Force. Will the Johnson motor tie into these controls, or will I have to replace everything, shifter included? I am hesitant to replace the shifter for two reasons. The controls that come with the Johnson motor have the tilt/trim button integrated into the shifter. My tilt/trim toggle is currently by itself in my dash, and I would like to keep it there for cosmetic reasons. The same with replacing the shifter...the boat's current shifter is just better looking. Any advice? Thanks guys!
