    Hello all,

    First post, but some of the engineers here really impressed me.

    I'm tinkering around with adding an electric motor to a 20 lb paddle board. The McMaster motor I'm looking at is 1/7 hp, 4,200-4,700 rpm and has a draw of 7.7 amps (24 volts).

    Is there a guess how fast it could go with a small propeller and a 200# adult onboard? To maximize speed, what kind of propeller would be best? What RPM would work best?

    Thanks in advance!
