Custom Bravo III prop socket. Very well-made, all steel and heavy duty. Uses 1/2" drive - Big end socket is 2 3/4" for inner prop nut. Small end is 1 7/17" for outer nut. Used for personal boat maintenance and is in like-new condition. Boat has sold and no longer needed. This tool really makes prop removal simple using only one tool. No need for two different tools to pull props. Local pick up only.
