I recently purchased a used 2019 Nautique 200. I was playing with it today (on the trailer) and tried changing the hydrogate setting. No visible response at the hydrogate regardless of setting. First question, is there some trick to making it move, or... does it have an interlock that only allows it to move when the boat is in motion? And, if it is broken, will this affect the slalom wake at all, or just trick? Thank you!
