Dave,
In the outboards I’ve seen with water in the fuel, and it happens to people ALL the time, one or more carbs don’t work and thus idle drops or engine stalls. My friend doesn’t do too many FI engines as he doesn’t have diagnostic tools computer testing or cleaning injectors.
If water is in the fuel for any length of time then it gunks up carbs or can mess up fuel injectors. I don’t know exactly how the injectors fail, he sends them to a dealer for that. That water, oil (2-stroke), fuel and alcohol really turns into a mess in an outboard carb. And on 4-stroke carbs can be bad enough to require replacement due to the extremely small ports they have. Even no water can mess them up if old fuel is left in them for a time.
