I have a 26' grady white with twin 200 2 stroke carb motors on it. recently i locked up the port motor and replaced it with a motor of the same year. my problem is that the motor i bought is what is called a comercial motor and all the plugs are different as far as the tach and guages are concerned. I would like to hook up my guages to this motor as without both motors hooked up to them the fuel management guage doesent work and neither does the tach on that motor right now. is this possible? the motors are 1996 one is a salt water series and the other is a regular precision blend 200. thank you
