Last trip out on the boat i noticed water in my fuel due to a bad anti siphon valve. So i had my fuel tank cleaned out and polished along with filling the tank completely up. So yesterday i took the boat to the ramp and tried powering up. Whats happening is the motor cranks but will not fire. So i brought it home and changed the spark plugs and fuel filter. Tested the batteries at the terminals and they were at 12.4. All the marinas in the area VA beach are booked up for at least a week. Any suggestions or things to try? thanks for your help

You prob. got water in the injectors. Optimax engines are very prone to issues resulting from water or other things in the fuel other than oil. However chances that they are all so pluged up that it wont fire are highly unlikely. Do you have spark? Voltatage is about right to be able to fire the engine. Check for spark and let me know.
