[HandsFree]

OK, so I lost my 3100 open a few weeks back due to a fire,everyone got off the boat OK. I had it perfectly set up for fishing so now I an looking at the 3500 as a replacement. Only question is the 3100 had great fish boxes in the deck which allowed for excellent access to the entire back, looking at the 3500 I see a sea in the back.  Can the seat be removed and is there a fish box underneath?  Anyone fish off the 3500? Could you give me some ideas on how you set it up? I really like the looks and the fact that they are diesel but not sure of their fish-ability.  Going to look at one this weekend to get a better idea of what they are like. Is there anything special to look for in the 3500, what about diesels? I have only had gas engines so I am not familiar with them. Thanks for any input you can provide.
