You should take a closer look at the clam shell cover on the bow locker drain. In your photo, it appears to not be positioned close enough.
I recall the proper placement is covering the drain hole 1/2 way. This position creates the Venturi (vacumn) effect and pulls the water while underway.
If the cover is not large enough, Perko sells 3 sizes. You may need to go up a size.
