RE: 2 blade or 3 blade
well first off you can not compare some loud gas boat to a fast electric boat.
you just can't
whether it's on a villain or larger 60 inch HPR 115 hull it doesn't matter. scale is scale and each prop is suited to its own boat.
i'm not really sure where you are going with this.
any boat will and can run a 3 bladed prop. from a 50 mph 6 cell boat to a 40 mph gas boat . and regardless of its power plant
