Possible causes for a Sea Ray 240 Sundeck with a MerCruiser 350 Mag engine to quit running and not start again include:
- Bad fuel - Issues with the fuel/water separator - Problems with the battery or battery switch - A faulty impeller (though it was reportedly changed recently)
These issues can affect fuel delivery, electrical power, or cooling, leading to engine shutdown.
