On a fresh engine, I would venture to say the scuff was from not enough piston to wall clearance. Marine engines need a couple extra thousanths to deal with hot pistons and cold coolant temps.
It usually takes a good bit more water temp than 230 to scuff a piston from overheating. Just my 2 cents....
