I currently have the 13p, but I’m going to put the 19p back on to see what it does. The engine has power to spare. At 4200 I was only able to get 28 gps speed. But I have a few things to work on. The underskining is off of it right now and I feel the water beating the floor boards, and the face of the transome so I need to build a transition piece from tube to engine pod to get the drag out of itGreat to hear. What prop did you go with and what speed were you able to attain?
