My equations only showed the futility of using battery powered electric

I was trying to point out the obvious and discourage him from this electric
nonsense when what he really needs is an old single cylinder 2-stroke and a
2 gallon gascan.

It's not futile nor nonsense. I've used electric for my dinghies since
1999 with success and happiness. Total weight is little or no more
than an old 2-stroke and extra gas.

I have no objection to an outboard, but remember he's in a situation
where he has no place to store it except in the home or car. A smelly
and very dangerous thing to do.
