Boats are loud enough... all you will do is piss-off other boaters, and probably get yourself a ticket from a ranger for being too loud. But more importantly... unless you can change the tuning of your engine... I don't recommend it since with less restriction... it will need more fuel at high RPM's.

Is there a "Cold air system"... as far as I know... no there isn't. The aftermarket filters are still inside the engine bay. If they were exposed to the outside air... you could potently suck in water into the engine.

Both ideas seem like a waste to me. You wont gain any power. It will only make it annoying loud.
