A piston for a two-stroke direct fuel injection internal combustion engine coupled to drive a marine propulsion unit is provided. The piston has a generally cylindrical body with one or more grooves formed therein. Each groove defines an opening to receive a respective piston ring. A thermal-protection coating is applied by anodizing the interior of the grooves. The respective region of the piston cylindrical body surrounding the respective groove openings is free of the coating.
