13 gallon tank
Hello Jonathan, I installed an approx. 13 gal gas tank in the outside lazerette. I am sorry that I don't remember the exact size of the tank, but what I did was to install a floor grid with stringers cut to the curve of the hull and affixed them with 5200. I installed on top of that a cradel made of angle iron and attached it to all points possible with metal brakets. It would be difficult to remove the tank again but I believe its there for a long time. Of course it has a topside gas fill, a vent to the outside and a bilge blower. The tank is actually under the cockpit floor and my entire lazarette is still usable now. Good luck. James I will try to post a pic if I can figure how.
