Mine is mostly stock.. My in floor tank is only 28 gallons, it's the biggest tank I could make to fit that spot. The tank is located between the seats, mid ship. I've heard that there are some with bow tanks, but I think they were all I/O models. I hear if you cut the front out of the tank well you can slide a bigger tank in (maybe that was you). I only have a 88 SPL on my boat and the 28 is good for most of the time. A 175 is a lot of ponies for that boat, it was only rated for 135. If I run off more then 15 miles to troll I put a flat 12 gallon tank under the motor well.
