I have a mid 90's 25 hp 2stroke tiller merc and i am attempting to convert it to wheel steer. I already have a console wheel and steering cables. What i am missing is the throttle components, cables, brackets and actual throttle arm/unit. What is the cost involved with this kind of conversion as well as how to go about it. What are the components i would need to buy to make something liker this work , if it is even worth the cost. I really don't have much knowledge when it comes to engines, but i am mechanicly inclined, so as much detail as possible would be greatly appreciated
