I have an old Envinrude outboard that I would like to identify the year and hp. It is all metal (no paint). Most of the decals are worn off. The only legible decal is on the front, which says "Evinrude Spor... Appears to be a 1 - 5 hp. Built in gas tank. 2 cylinder. Exposed spark plugs in front. Pull start pully on top (no recoil)which is stamped Evinrude Motors. Single transon mounting bolt. The name plate says Envinrude Motors, Milwaukee, Wis. Model or Serial # 4287-01193. Has a number casted into the cylinder body of 101828. Thank you. Fred
