While regular Seafoam can help control moisture in your gas and it's really good stuff, it's mostly a detergent to clean the fuel system. It can't hurt to use it, but there is very little alcohol in it to bind with the water molecules and burn it off in the engine. There are other alcohol-based products like Heet, Sta-Bil 360 Marine, STP Water Remover or even generic Gas-line Anti-Freeze and water removers that will remove water in your gas better.
I always throw an entire can of Seafoam into my gas tank when Pearl comes out of Winter Hibernation to clean the varnish out of my carbs. If I got water into the carbs I would go for something like this:

Just some food for thought.
My old school experience also tells me that gas line anti-freeze products lose effectiveness over time so don't keep it on your shop shelf - Buy some new when you need it, like brake fluid.
