Lots of youtubes about this topic...
I'm looking to propel my ~100 lb (~45 kg) dinghy to a dock from a moored boat - and back.
Current is tidal and can reach 7 knots.
Bought a cordless drill (always wanted a cordless drill):
The prop is from this fan:
Added a 3' X 5/16" stainless threaded rod, 6" stainless carriage bolt, 1" PVC pipe, 1" delrin bushings, a 45 degree PVC coupling, and some bendy, steel mesh reinforced rubber tubing for attaching the rod to the carriage bolt inside the 45 degree coupling.
Initial sea trails went better than expected - reached ~3 knots in calm conditions.
The fan/prop is a bit bendy so I've given it a coat of epoxy. Will see tomorrow after the epoxy completely hardens.
Not sure if folks on this list are interested in this type of electric propulsion.
