what prop moves more water
This is based on the fact that the motor will have no problem spinning any of them and doing it at 33,900rpm so what prop will rocket this little boat the fastest all opinions are welcomed

RE: what prop moves more water
Moving more water means increasing thrust. Picture a huge prop rotating at 100RPM. There will be tons of water being pushed but pitch speeds will be extremely low.
If you are looking at speed you have to consider pitch speed. Pitch speed is determined by the RPM under load and the pitch of the prop. A higher pitched prop will move the water faster than a lower pitched prop. High RPM, high pitched props usually do not have high thrust meaning they don't move a lot of water.
The theoretical fastest prop will be the one that has the highest pitch and least resistance in the water.

RE: what prop moves more water
well I tried them all it goes in this order high pitch 2 blade low pitch 2 blade 3 blade 4 blade the high pitch 2 blade is stock so all the props failed the three looked promising until it began sucking air like crazy so the stock works best who would have known
