RE: good airboat motor
Not just a bit big the hull would need to be huge a guy in my club has one in a plane an 80cc the power is amazing he can get his plane to hover just like a heli but in an air boat would love to see that in the water
but the only thing that is a draw back it is a petrol engine spark plugs do not like water need to use tons of ignition sealer be on the safe side but that will go like a bat out of hell
