No custom gas tank. Bass Pro shop has a good selection of tanks, but the one I wanted when I was building was out of stock, so I used the old stand by. I should have added, I also installed a small screw out "hatch" to acess the gas tank.
I was also concerned about cables for the batter back to the control panel and motor heating up. The heaviest gauge cable I could find for the money was a pair of long jumper cables.
The running lights I picked up from Fleet Farm, an aftermarket accessory for a car, looked for the cheapest, sealed, lowest power draw ones I could find, about $20.
Sorry no pics of either, will take some over the weekend and post on Monday.
Having thought more about possible changes. I would now like it to be about 2 foot longer and somewhere around a foot wider, with a 60hp on the back. We normally hunt three guys out of the boat, across the side. The guy closes to the bow, cann't stretch out his legs straight. And little longer would offer more room for stuff.
