Replace it. Check to make sure the crank and bearings arent damaged. Check crank index as well. You will spend less fixing this one than you will buying another ski that could blow up tomorrow. Get this one fixed up right and you should be good to go for years to come.

Also, this piston is the only one beat up before putting the other cylinder in, what should I do tuning wise?

you should probly rebuild ur carbs and install a three output fuel pump, because it looks like your piston burned up from being too lean, and what did u mean by burn a hole in the carburator?

If you ran it long enough on two cylinders the carbon may have washed off from the raw fuel?

You said in you first post that you had been running it on two cylinders "the last few lake trips"? Did you run it a while after burning the piston? If so the fuel would still enter the cylinder and wash the carbon off.
I may have missunderstood.
All so Im assuming you have a 3 cylinder engine?

it sounds like all your pistons are lean, so when the first holed and you ran it for a while there was still fuel going into that cylinder, the raw fuel that doesnt get burned then washed the black carbon off your piston, you need a fuel pump upgrade then some carb tuning, to get your wash right
