Default Disable water in fuel alarm?

Does anyone know how to disable or clear that alarm? I have emptied the filter, on the motor, and the Racor. Also, turned off the power to the batteries.
That worked for about 20 minutes and then that annoying alarm started again.
I have a pair of 2014 Yamaha F-225's.
Thanks

I'm not a Yamaha technician, but I would be inclined to repair the "false" alarm to protect my expensive engines.
Where is the probe or sensing device located? VST? If so, can you determine which engine is generating the alarm? You have a valuable diagnostic tool with twins (as long as one is operable). Good luck!

Alarm is sounding on both engines. I don’t think the fuel filters were changed after the last water/fuel problem. That should fix the problem.

I second this... unfortunately from experience 😥

Your tanks are full of water.

The "sensor" is a float that floats in the presence of water and switch in the bottom of the engine mounted fuel filter. Remove the engine mounted filter and dump it into a clear container. If you see any water, remove all of the filters (engine and boat mounted filters) and dump the contents. The boat mounted filters have to fill with water before you get water to the engine mounted filters. Repeat this process immediately whenever you get the alarm (it may take several times to clear the water in the tank). If you've run the engine with a substantial amount of water in the engine mounted filter, you also need to drain and clean out the VST.

Check your fuel fill o-ring, tank vent, or other sources of water in the fuel.

Be aware that if you keep running the engine with water in the fuel, you will damage the injectors, cause corrosion in the fuel system, and ultimately destroy the engine from carbon buildup.

I agree with what others have said. Get rid of that water.

But if you need to just stop the alarm, (at least on smaller Yamahas) all you have to do is unplug the wire that goes from the bottom of the fuel filter canister. You have to unhook it to take the filter off, so there's an easy quick-release for it.
