If proped for twins, I totally agree. Just as no twin setup will deliver x2 the amount of HP that a single will. (Two 70 hp engines will not give the equivalent speed of a 140 hp single). But it still doesn't answer the question.... What hp does a V20 require in order to break free and get up on plane? Let's presume he has one engine go out, so he raises that one, and changes the prop on the other one, and it's a dead calm day on the water. Will the one 70 be enough to get him on plane? I seem to recall somewhere that someone in here had a 90 hp engine and they claimed they could get up on plane, and I know from personal experience that a 65 hp engine just will not do it. So what's the minimum hp necessary?
