I have a 1996 Mercury 3.3 HP 2 stroke outboard that does a decent job.
Recently, I ran aground and chewed up the prop. I need to replace it
but here's where the question popped up. Is there a way to increase
the speed/power of this motor with a different prop (or any other
means)?

I see that there's an optional Black Max prop for this outboard but I
don't know if it make any difference except in price.

Is there anyway (prop, fuel, plug or anything else) to increase the
power and speed from this outboard without having to buy a higher
horsepower outboard?

I'm hoping that there's a way without damaging the outboard. Any
experience or suggesting would be greatly appreciated!

I bought a "15" hp Mercury (maybe Johnson) that was camoflage painted
for duck hunting. One day the sun was hitting the cover just right and
I could see a slightly raised "10" under the paint. The seller
admitted it was a 10hp with a 15hp carburator, he said that was the
only difference between the two. Most people I asked said that was BS,
but a real trusted motorcycle mechanic said it was quite possible, so
maybe you can put a bigger carb on yours.
