Ahh.......Thats why I love my vintage 75! No floor gas tank!!
I have 2 fish boxes that will hold 100 pounds fish+Ice!! That is of fluke, sea bass, scup, and 4 Bass each.
Thats 200 pounds with out taking any deck space!! :P I also have the step down with a cover on it and a plug for the floor there also, just incase i have a over flow.
O yea thats a 25 gal tank in the engin whell and 2 20 gal in the side gunnle tanks.
