    Brett > PRO STAFF <

    Dual thrust propellers are designed for use on outboards pushing a heavy load.
    Usually found on engines pushing pontoon boats and displacement hulls.
    Not really intended for use on lightweight planing hulls.

    I have one on my boat (Mercury 25 bigfoot) and it will push a ton - literaly. Don't get speed out of it but it will not bog down. Used to be on a 20' jon that carried nothing but a semi load of decoys - around 30-50 dozen (easily 1,000lbs plus).

    As usual - Brett is correct.

    I have run the motor with a 8.5 x 7.5

    I want a 8.5 x 8

    the DT is 9 x 7

    I hope to test it this comming week time and weather permitting ;-)

    Brett is right.

    I own a 21ft suntracker pontoon boat with 60hp merc 4-stroke EFI BIGFOOT model and it's has tons of power to push the pontoon boat.

    One time I have my friends ride with me and my buddy's pontoon boat.

    I have 5 people in my 21ft pontoon boat with 60hp merc bigfoot 4-stroke EFI push around 21 MPH.

    My buddy has a 20ft pontoon with 70hp 2-stroke yamaha with 4 adults, coolers and stuff like that. It's bogged down to 15-16 MPH.

    So u don't need to test dual props for your microskiff.

    Get a different propeller like a 4 blade prop and ajackplate or whatever to help out your load.

    All that high tech equipment and yet love the retro 70's shades.

    Glad you had success with the prop...how do you like reverse...can you say brakes!

    well since the 13 footer has a flat transom did not really try reverse much... but the Bow does not seem to dive at throttle chop like a Normal prop ... Now I need to buy the "special" Nut lol ....

    The high thrust props give good improvements in forward - keep bow down and lift the aft right into position - but give HUGE traction in reverse compared to stock. I have used mine for brakes (lock motor down, hold on and hope you don't care if you get wet. ;)
