Re: Gas Tank under the deck vs. not
There's only one con and that's if you plan on relocating to a different part of the boat. That will change the balance of the boat and may cause it to ride oddly. If you can get it below deck in the same proximity as the current tank it shouldn't be a problem. You just have to remember that you have to fill it and vent it so choose a location that will let you run hoses to it.
