You may have partially seized the engine from being too hot and loosened up enough when it cooled down.
This is a cooling water concern, a slightly low oil level would not cause an overheat , most likely the oil pressure alarm would go off first ,check your fresh water cooling system, drive belts, sea strainers, valves, thru hulls for blockage.
Your engine may have survived but with a couple of years taken out of its life.
