This boat now has an EFR6758 turbo and produces nearly 300+ more pounds of thrust than what it is producing in this video. It can literally go anywhere. With 2 people on board it's unstoppable. Not even 7 people on this boat with a total weight well over 3400 lbs can stop it from moving on dry ground without shaking the rudders.....Proof is here: https://www.youtube.com/watch?v=ObFjJ...

Still on the stock turbo we put some time on the Ox Drive with a good wingman along so we could test the limits further. The improvements over the previous PSRU are very apparent when driving the boat, the Ox Drive is very superior. The running conditions vary by the foot almost in this area of the river and one moment the green grass or black mud is very difficult to run through and 5 feet later it takes less than half as much thrust to move the boat. These unpredictable and constantly varying conditions require an on/off throttle that with the previous Rotator PSRU caused a lot of vibration and harmonics that the Ox Drive is nearly entirely without. Again, vast improvement and further refinement is still in the works.

Prop: Sensenich 82" 4 Blade R
Hull: 14x8 Al David 7075
