Do you have a float hooked to your boat keys? I do on mine. Took my smallest grandson out on my brother's pontoon when he was 3. He walked by the keys and reached over and took them out. He said, Grandaddy look what I got. I of course, like to fell out of my chair when I saw them. I said real calmly bring them to Grandaddy. He looked at me, smiled, and threw them out of the boat. Thank God my brother had one on his keys, or I would have had to go swimming that day.
