Absolutely and issue if there are hordes of old 235hp OMC two strokes running all over the place burning 20gph each. But we are talking little dinks that might burn a couple gallons a YEAR.

Old 2 strokes are nasty for a bunch of reasons - of course bigger ones are proportionally worse than smaller ones. Newer EFI 2-strokes are somewhat better, but there's a reason the old carbureted 2-strokes are banned most places now. About 25-30% of the fuel is not burned and goes into the water - think about that whenever you fill the tank. Moreover, the combustion byproducts are way worse & persist for a long time.

In remote areas I might buy your argument that this pollution is so diluted as to not matter, but in the areas where a lot of us cruise, which are already under heavy environmental stress, I don't think it's conscionable to use this technology if you have the means to buy something better. Again, there's a reason these engines are banned.
