I am planning to build an electric pontoon boat. I would be using it on a shallow harbour bay with lots of sandbanks, which is why a jet seems like a good idea to me rather than a propeller.
As far as I am concerned, the easiest way to build my own, electric jet drive would be to buy a DC pump with something like 4kW and position it cleverly on my pontoon boat, powering it with lead acid batteries. I want to make it electric, because it will need to recharge by wind rotors while moored. I am trying to achieve a zero-maintenance cost boat, or something approaching it.
But would that work? And would it be reasonable? Or are there better choices?
