Need help...going to get a hot foot for my dad for Christmas and am unsure of the length of throttle cable I need to buy. Am going to get the adjustable plate cause I am 6'5" and he is 5'11"...also has a 6" jack plate...not sure if that factors in to the length. Tried to call Triton and put on hold for 45 mins before giving up. Anybody done one of these before?
