I'm tired of grinding gravel & rocks so i'd like to put a jet unit on my 50hp yammie 4stroke. I think the swap of the lower units would be quite easy but i have a center console on the boat (18' G3 ) so i'm wondering what gets done for the forward & reverse cable? do i have to lengthen it to reach down to the jet or is there some kind of linkage that goes from the motor down to the jet. Oh yeah one other thing?? who's got the best deal on a jet unit in town??
