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).
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.
