Well just a quick little update. I thought about mounting the tanks in the side sponsons. I made the brackets ans was almost ready to install them then I felt the bottom of the boat. The boat is super light lay up and the bottom is pretty thin. So after some searching and measuring I decided to go with a stack tank. I surprisingly have a good amount of room in the boat. I was able to find a bitchen set up moon stack tanks. They do not have a big diameter tank which is good for room. Here are the only pictures I have since the tanks are still in boise idaho.
