Hi, I have the same boat. It's a very common problem with the Trophy's of the 1990's.
Those are not drains. On your helm, you should have a switch for the Fishwell pump, but most of the time, the pump does work well or at all. It will get pumped out of the aft starboard side of the boat if the pump is working. The flsh lockers are a terrible design and they are not sealed properly so you will always have water in them from rain or washing the deck. If you have not already done so, you'll want to change out your stock scuppers with the ping pong ball type because water will come in through the scuppers when you have too much weight in the stern and will also fill up your fishwells.
