Ralph, just for info, I just repowered a 76 CC with a 350 Marine Power 315 HP carb and it appears with the flow scan, I'm getting better that 2 miles per gallon and running 28-29 MPH. I got the carb due to the fact I can figure things out if required. The prop is a 17" X 16 and will turn up 4600 RPM. Also the packing I used is the newer GFO packing and as many times I played with the prop (disconnect shaft from trans to eliminate the banging effect) does not leak (I'm surprised). I'm not sure if the tunnel would be a problem since boats are made now with a setback (Fountain) and they do this for clean water and can run the motors higher. Good luck with you decision whatever you do. But I do like my ride with the inboard.
