I suspect the issue of "engine trim" is a red herring. I take it you're having this problem when the boat is at rest, sitting to deep in the water because it's full of water under the the deck.
If you're meaning "spray" rather than "green water" coming over the transom then I'd look for damage to the engine leg, cavitation plate, transducer or pito dislodged or damage around the tube seams near the transom.
