I have a 2004 SC 1652 G3 welded boat with a Prop 60 hp yamaha 2 stroke 2003 model. I bought this rig new in 04. Our local river gets low in the summers and it exposes sandbars and some rock ledges. Well I have been thinking about moving my consoul to the front and center. And converting it to a jet drive. To raise the transom I thought I would get a jack plate. One reason is I could switch back to prop when I go to the lake or the rivers up. That way I can enjoy the extra power. Does this sound like a reasonable set up. What speeds do you guys think I will get when I switch to the jet. I am around 35 with the stock prop. All help and advise will be appreciated.
