Here is a small outboard motor that requires no fuel, just a little oil... elbow! Indeed, the Australian inventor had the idea to mount a propeller on a flexible hose at the end of a crank. You just have to turn the crank to make the propeller turn.

To make things worse, a mini gearbox (installed just behind the crank) with a ratio of 3 to 1 increases the speed of the propeller (for one turn of the crank, the propeller makes 3 turns).

This product is primarily intended for use in appendices. No more oars taking up space on board. With FreeWheeling, anyone can get by. No need to learn.
It is also a safety product that can be safely left in a child's hands. Lightweight (3.5 kg), it can be fixed with a simple press screw on a transom. A steering locking system (one screw) keeps the propeller in the axis of the boat. Loosened, the propeller is then used as a rudder, like an outboard.

It's very simple, very basic, but cleverly thought out. Probably the most innovative equipment for this 2017 season! Especially considering its price of 159.90 euros including tax. 10 times cheaper than an outboard engine..
