    is there a way to build a mud motor out of a bottom shaft motor?

    I have ponder this quite a bit.

    The key is a good right angle gear box with a 1:1, 1.5:1 even 2:1 reduction.

    I have done some searching with not much luck. I have thrown together some thoughts using spiral bevel gears and machining a housing, like that of PD. I have also thought of using an old outboard lower unit.

    I can find plenty of 16-20 hp vertical shaft motors.

    If there were a good gearbox off-the-shelf (not too expensive) the rest of the build would be easy

    Looks good.

    You got any baffles inside that exhaust?

    Yes it can be done. Use a simple helical ring and pinion for the 90 degree turn.

    Some body builds everything.

    Would it be affordable? - Probably not. It is cheaper to buy a horizontal motor and use one of the excelent belt systems that are out there now.

    3 alternating baffles with about a 1" overlap in the center. Good deep sound with about a 150 rpm increase.


    Unless you can find a in-expensive gearbox, belts are much less expensive.
