Water over transom

Hi everyone
New boy here,based near Oban at port Appin. Been using sibs and ribs fo a while,and thought it a good idea to join Ribnet. I may need some advice, as when I trim out the engine a 75hp mariner on a Humber attack water starts to gulp over the transom until I continue to trim whereupon it eventually stops. This started happening after it broke its mooring and fetched up on the rocks nearby. I canít see any thing bent or broken and the engine runs fine. Anyone got any ideas?
Charlie

Welcome to the forum Charles.

Get some pictures up of the boat in the water so we can see what's what. One obvious question: the boat hasn't shipped water when it broke from it's moorings? You'd have to retrieve and check the hull drains.

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.
