Exhaust H2O Injection for Torque

That is an interesting idea. It does sort of make sense. The three issues that could raise are: what would this do to the cat? would this increase rust? and I can't imagine that this temperature fluctuation is going to be good for the exhaust system. Maybe that stuff doesn't matter or is insignificant, I don't know. This is something to look into though.

I'm picturing something that only works at very low RPM like crawling or red lights. I slip my clutch a lot rather than fall out of the power band when starting out. It would be nice to mat it at 1000RPM and take off with authority. How much water it takes I don't know. I guess you'd have to calculate the calories your'e trying to extract from the exhaust flow to get a number on water consumption. I do know that racers wrap header pipes to keep temps up by a few percentage points and help flow speed. Regular water injection takes 10-20% of the fuel consumption figures if your'e really using it alot.

...The idea is to inject water spray into the exhaust chamber. ...
Did you Done That?

You would be better off with water injection before combustion.
Boats dont have expensive pipes and cats (yet). Not to mention if parts rot out on a boat, its accepted as normal wear and tear.

I say you get more power from:
Water injecting pre combustion, which allows you to run more ignition advance without pinging, which opens up more power for you, and just leaving your exhaust at a more conventional size.
than you do from:
whatever slightly larger exhaust you can run without losing your scavenging qualities by injecting into the exhaust.
I also say: HOLY OLD THREAD, BATMAN!! but this one is actually kinda interesting :-p
