Fuel tank replacement

[Briguy]

Trayder,

Thanks for your advice but adding more weight is not what I am after. I had thought about adding a few small bags of shotgun lead in the bow for about 50lbs and that might do it. As far as resale on fuel capacity. I see many i/o& inboard boats on this site with 95 to 120 gallons of fuel. Range? I can go 60 miles off shore, troll all day, come in and still have 30+ gallons in the tank thanks to my 4 strokes. The days of burning 15 to 20gph are over. My previous twin Yam 130's averaged 1.7mpg total. Now I average 3.1 mpg total. No need to carry the extra fuel weight. How tough of a job is removing the console and yanking the fuel tank? I will either have the tank shortened by 2 3/4 feet(from 8+) or just get a new tank? Any suggestions?
