Well my boat comes in today , I will be running it tonight for sure . I will try the 440 prop on it and prep the inside so it is water tight . I do have a ques. though ...... People have said to sand the bottom of the boat with 400 grit paper for stiction . I know on real sail boats people have done this because the entire hull rides in the water but most boat hulls leave the water at high speed , usually only a small portion of the boat is in the water . wouldn't it create more drag on the hull by roughing it up ? I usually teflon the bottoms of my boat hulls , get them slick as possible and I get speed increases by doing so , I have checked by gps . Anyways just wondering about the roughing the boat bottom .
