this would be a stupid mod for those with kids that frequent a boat. I have not had anyone under 14 on mine in 2 years so I would not have any issues doing this, but I'm not sure what the "true" benefit would be. keeping spare keys in the tow rig and perhaps one in the jockey box should prevent any lost/forgotten key issues.
the argument could be made that I might have a kid on the boat in the future, but if you have a kid on my boat and they set foot in the drivers seat uninvited, both kid and parent that are not watching the kid are on the closest dock done for the day
