It could be a silicone job faulty at the factory, it could be the livewell flush valves open on the rear of the livewell (simple). There are dozens of places it could be and since its new it could be either us or the dealership in rigging. In 2015, during a 2 month window, we did have some silicone inefficiency on drain plugs, jackplates and thru hulls. We solved that problem in house though there could be some remaining in the field. We really can only speculate as to what the issuers if its not the livewell valve. You also can not run the pump in and aeration full time. The pump n is only for filling the wells, once they are filled the aeration and recirculation is all you need. The overflow on the wells can not keep up with volume. We apologize for the issue on a new ride and we will be glad to help any way we can. Opening the rear lid and paying attention when sitting on the water may show the leak if you dont find it easily.
