If you cranked and cranked without closing the sea water intake you've likely filled your cylinders with water. Was there water coming through the air intake? Did the engine lock up?
If no, you were lucky. When you get back to the boat open the compression levers, close the seacock that feeds the engine and try to turn it over. If it turns over go ahead and bleed it, crack everything from the injectors back to the filter. Work from the filter to the manual pump, till you have a stream, no bubbles, then through the fuel pump. After the fuel pump have someone turn over the engine for you and close the injectors one at a time. When that is done throw the compression levers back on one at a time after it begins to fire. PS, don't forget to open the seacock.
If its hydrolocked, call a mechanic asap.
