Bilge Pump Tower, i have about 6" between the Main Fuel Tank and the Transom so stacking them was a great solution, lower pump is my primary pump, upper is the secondary pump, both on floats. Primary illuminates a LED light on the dash, secondary pump powers a low pitch horn, important because we spend multiple nights tent camping on the lake and as far i i know, nobody has ever heard a boat sinking...
I recycled the Nautolex Vinyl floor covering, recut it to fit and follow the new Stringers.
12gal Aux Tank serves 2 purposes, of course extra fuel but also ballast to counteract the Engine Battery & Vessel Mounted Trim/Tilt Pump. You will see the Tank on an angle. The angle was necessary to keep the casting deck floor height as low as possible. The fill neck was the highest point of all the underfloor components. The "pan" that the Aux Tank is resting in is recycled transom deck skin.
