I have a 24ft Harris pontoon with a 1997 yamaha 40hp. I have found a nice low hours 70hp but is several years older. According to the model number, the 70 is a 1985 model. The boat has the 704 top mount control. Does anyone know if this will work with the 85 model motor? From pictures it does look like the length of the cable rods under cowl is different, but these do appear to be adjustable. I would like to just plug and play and not change controls or ignition switch.
Thanks
