I had the same thing happen with a Volvo engine in about 1990.
My boat was in a boathouse in an area that continually gets waves. Somehow the waves against the stern allowed water to go in through the drive, through the exhaust headers, and get into the engine. When I attempted to start the boat, the bolts on the starter broke from the torque because the motor wouldn't turn. Water doesn't compress easily.
They had to replace the starter but eventually put different exhaust headers in with a hump in them. That prevented the water from entering the engine.
