Pbain you will need a 25" I belive. You measure from the top of the transom were the motor will rest down to the very bottom of the boat (center) this will be your shaft leanth. What size shaft do you have on there now??
I have repowered with a Yamaha 175 and a gill bracket. I have used it anough now to coment on it. I LOVE IT!! I get 5000 rpm and I get 40 mph when I am alone. I curise at 4000 to 4400 and go about 32 to 35 much nicer then the old I/O. Now I am not sure on the excat milige but I go from Green pond Falmouth to Laucs Shgolas which I no this is a 13.5 mile run one way. 27 mile round trip plus all the running back and foruth after a drift. One day of this I use about 15 to 18 gal of gas. The old I/O used about 13 to 15 so I feel that I am doing ok.
