    More ideas in the thread "efficient electric boats" on this forum, pg 12 and beyond.
    Torquedo has some 2 and 3 blade props which can be purchased as replacement parts. These should be very strong and possibly adaptable to your project as well.

    And alas there were no 15x25s to be found.
    Here is a list of the Bolly props I could find,
    16x13w, -2 blade
    16x14 -2 blade
    16x13 -3 blade
    14x14 1/2 - 2 blade
    There is also an APC 16x16
    any thoughts?

    Oye I also noticed that I was misreading the power chart on the motor.
    It produces about 5 HP at 800rpm at 24V and 300A
    I was reading the Efficiency of the motor not the NewtonMeters of torque.
