so when i put it into forward one i start to throttle up its smooth then it gets tougher more force to get it wide open so my question is should it be smooth and the same the whole way or get tougher i have had to work on the carbs so maybe linkage adjustment but on the water it runs fine no crazy issue i idle or anything but same issue with the control being tough could use new cables are these available for this old control box




so i think i might have answered my own question if i unhook the throttle from the motor the control box is smooth and easy hooked up not so i think its a linkage issue but also were can i get cables and what info do i need to find them model serial number what because ill probaly get them online local marina isnt much good for this old boat

I believe cables are available on this site. Most of the time the length is marked on the cable itself,if not measure.With cable off does the throttle control lever on the motor operate smoothly?
