There had been some chatter here in the past, but nothing I can find recently. I have a Boston Whaler that, terribly, I never use; I also have a goodly supply of PV batteries from an earlier project (Pb-acid....heavy...but on hand). I'd be quite keen to learn more about any close-to-feasible conversion that currently exists. Surely there must be some kind of prop-driving electric motor out there? I also happen to have a number of minuscule electric trolling motors (Minn-Kota), but even if all 3 or 4 of them were in good order they'd not be able to push the Whaler very far for very long or very fast. Any help, anyone?
