Yep 33 main tank under seats, 10 gallon kicker, dont forget you have a fuel window located under the drivers seat between your legs to visually look at the main tank to see the level in it, usually best to do this in sunlight to see the level. The ten gallon kicker tank is in the bilge area. Dont forget when using the rear tanks you need to switch over the valve (to the “right” tank) in the splash well and change the tank selection setting on the touch pad panel to the “right tank” to get acurate readings on your gauge for the rear tank. The touch pad will automatically default to the left tank when the power is turned off then back on. Also remember when fueling (topping the tanks off) to leave approx. 1 inch to 1.5 inches from the top of the tanks to allow room for expansion of the gas as the temperatures begin to warm up, and when storing the boat lower the jack to allow the boat to sit level, so that in the event of gas expansion it doesnt come pouring out of the vent for the rear tank.
