the boat is a sk-daddle too, 27 inch flatbottom, most likely going to be surface drive when it hits the water, engine will be a cv.12 out of a buggy (.56hp) then I might switch to a cvr.15 (1.2 hp) until I can afford a nice .21. thinking about just using one of the mac tuned pipes on it. the boat should weigh about 3-3 1/2 lbs ready to run, and only sits about 1/2 inch in the water at the transom when floating in the bathtub.
