Humminbird 899 SI transom bracket snapped off, not sure how but its irrelevant at this point. Cant find one locally before my tournament on Sunday. Im sure its possible but id like to hear from someone maybe who has done it. Maybe some galvanized brackets from a hardware store?

Crude but it works. Attach the transducer to a wood board then C-clamp it to the transom.

Academy sports near? They carry them
