Also need to drain out all fuel from the fuel tank and clear it up.

Check it the engine oil, there is also trace of water.

Replace with Mecury engine oil, and clear the injectors.

Lucky, the engine is not damaged, it started again.

The fuel cap O-ring and pipes are all in good condition. So the water can be condensed from air ventilation, or in the process of filling gasoline, even in the gasoline itself.

A good solution is to fit in fuel line a fuel water separator. Axopar 24 is a relatively compact boat, need to find a ease access place to install a fuel-eater separator.
