Your gona need to power it with your legs instead of your arms. Waaaay bigger muscles in the legs. I gotta say that I think freediving fins really nailed it on this one just get a pair.

This^

The fully evolved body-powered mechanism is fins, maybe some kind of hand-fin could augment that.

There is no shortcut to get more out than you are putting in or to radically change the way the force is being applied. Experiment with making your own underwater electric scooter/powered person-dragging turbine perhaps?

Obviously not the full answer, but this is a possibility:

swwweeetoo.

This is givin me some concepts I can work with

Just get a 30lb trolling motor and a waterproof li-ion battery pack. Attach handles or mount on back and bingo.

Yep. Second the trolling motor. Inherited a second one and tore it down added handles and bat pack and goes well. Built a cage around prop after testing nearly took my ear off.

Every half cycle, just turn around 180 degrees and swim away.
