Welcome to the forum. To tell you the truth 115lb's isn't bad at all. Let us know what your elevation is.
When you suck it water, it's a good idea to turn it upside down with the spark plugs out and kick it over. That will allow most of the water to be flushed out. The biggest trouble with water is that it can bend a rod. Not super common, but it can happen. You can also blow the head gasket.
Check all the connections in the wiring for corrosion, make positive sure you got the carbs clean. I dought not much if any actually made it into the carbs unless it was in the fuel tank. Put new gas and plugs in. Make sure the coil wires are in good. Fire it up, blip the throttle for a little bit. You don't want to rev it to high in case water is in there. If it doesn't smooth out after a little while you may have more damage... but I dought it with the compression being so close in each cylinder.
Keep at it. I dought very much if any debris made it in if you had a filter on there... just the water. Make sure the pipes aren't full of water too. The won't be for long if you get it running
