I found them online, the Center Harbor Yacht Club. " Visiting dinghies may tie up on the inside of our floats, but outboard motors are not welcome." This is clearly an exception, by a long shot, lunatic fringe. Probably has near nothing to do with outboard noise or pollution.
This has not been my experience, at all. I tie up in lots of places, typically from Nantucket to Montauk, and I confess I haven't seen a sheen on the water even when the dinks are three deep.
I got the impression it was all about sailing there, and so they discourage/ban 'machinery.'
So, you got me looking into this. It seems Amsoil has an oil that they say works in outboards at 100:1 "regardless of the mix ratio specified for the equipment."
There may be a geological component to this. Island and open coastal areas get better circulation because of the geological features that allow wind and current to flush the local waters. On coasts like Maine, where inlets and bays are cut deeply inland and often have numerous islands and convulsed shorelines restricting the flow of water and the blowing of the winds near shore, surface water hangs around in stagnation between tidal flushes. Even with the large movement of tidal water, the few inches on the surface can hang around against the shore while deeper water moves in and out of the bay underneath. Just try to pour the top layer of beer out of your glass to get a fly out and you have to pour a lot of beer from underneath that fly out before that top layer moves enough to evacuate the fly.
That beer analogy got me thinking it's almost 5:00There may be a geological component to this.

I was referring to "currently made and marketed" rather than to the ones for WWI and WWII but I guess I wasn't clear on that point and when I wrote "made" I should have used "being made." If I recall correctly as of a few years ago I believe Germany was making a small "coastal defense" marketed submarine for the military export business. You are absolutely correct that Diesel-electrics were the only subs used in WWI and WWII and I did not mean to imply otherwise. My point was that they have their place, just like all electric cars, but they have their limitations including range, duration when solely on electric power and that charging "on shore power" would not be practical. That's all. I appreciate your clarification although I don't think I was "incorrect", just unclear in my use of verbs.
What source do you use on your boat? How long does it take?How do you charge the battery?
Optionally 12/24v.

Both involve cutting something off to solve a problem. I see the similarities.That's like saying a hangnail is right up there with decapitation.
Years ago, one of the motorcycle magazines did an article on 2 strokes. They experiemented with all kind of different ratios. What they found was that 20:1 produced the most power and 16:1 produced the least amount of wear. How much wear occurs, and where the knee of the curve for excessive wear occurs, I don't know, but I can't imagine using 100:1. Maybe it won't seize, but I have to think it would shorten the life.
I can't let this one go without questioning your sources for this? (Sounds like oil lobby propaganda.)
