Auto Full Power Reverse

Introducing the World’s First Full Power Automatic Reverse

Pro-Drive reverse outboard mud motorThe very first Pro-Drive was designed with reverse in mind. Knowing the problems with using the conventional outboard reverse in swamp conditions, a different approach was taken. Rotating the motor and lower unit 180 degrees like the old small outboard motors seemed to be the simplest, most effective, and most trouble-free method. However, fuel and battery connections, controls, and a hot muffler seemed to disagree. So it was decided that the lower unit would have to rotate 180 degrees while the powerhead and controls remained with the operator. At the same time the drive shaft and the lower unit drive shaft would have to remain together and perfectly in line. We realized that most situations boats get stuck in are when forward power has no more effect due to the boat being on top of heavy vegetation or ground, or there is no way to turn around.

Propellers are designed and tested again and again to get the most power and speed out of a boat and motor, going forward, not backing up. What happens in reverse? The propeller is rotated backwards and some reverse thrust is achieved, but only a small percent of when the motor is in forward. What happens when a backwards rotating propeller contacts an obstruction? The trailing edge strikes first and “hooks” the obstruction, often bringing the motor to a complete stop. On surface driven mudmotors, due to prop design, reversing the propeller is even more ineffective than conventional outboard props.

When a Pro-Drive is in reverse the skeg is in front protecting the propeller just as it is when in forward. The propeller is still rotating the same direction, the way a propeller is designed to work, giving the real power that the motor is capable of, while the “round leading edge” glances off of obstructions. Water is forced under the boat, between the bottom and whatever the boat is stuck on. The rear of the boat is lifted. The capabilities of Pro-Drive’s full-power reverse can only be realized in the many swamp and marsh situations that without it, a shallow water outboard becomes immobilized. Take a ride in a Pro-Drive with full-power reverse and find out.
