This is a fun from a vintage O’Brien single waterski. It is aluminum, featuring paint in amazing shape. This would make for interesting decoration or a replacement part.

Logo is 9” long and 2.25” wide.

Fin is 7.5” long, and 2 3/8” deep below the board, allowing for 1/2” of board thickness.

Six bolts hold fin to board, and they are spaced at 1 1/8” laterally, and each at 3 9/16” front to back.

Thank you for looking!
