I've brought a trolling motor with me, with the intent to add electric propulsion to one of these. It'll be powered by a pack of 4 half-dead Thunder Sky lithium ion batteries from an electric scooter I used to have.
It's nothing special, but you gotta start somewhere. It'll be used almost exclusively to travel less than a mile between the docks of various relatives who own nearby cabins on the same island.
Next year's project will be getting the cabin offgrid with solar panels and a power wall, to save on the $500/yr it costs just to keep the grid electricity connected. >:I
