Where to place batteries/gastank (first boat)

[deezdrama]

Just boat my first boat (15ft smokercraft basscatcher) and going thru things getting it ready to take out.

The seller just had the 6 gal tank sitting infront of the back bench, i want it behind the bench in the transom compartment but need to know its ok to have gas and electrical connections in same area (worries me)

The battery box is bolted on the right and the bilge and livewell pumps are on the left side.
Gas tank will fit on the left but then it sits right ontop of the pumps.

I have my own brand new deep cell battery and box id like to add to the existing battery for longer battery use (2 trolling motors,pumps,lights, might add a small stereo system and spotlight and fishfinder)

Will two 27 bank 105ah batteries be sufficient?
And should i seperate all electrical to one side?
Safe to have both gastank and batteries behind the back benchseat?
Thanks

Also... should fuel line be cut short as possible? Its about 5ft long and only need a couple feet

batteries should be fine... ive always had my battery and fuel tank behind the back bench together with no issues (battery in a box). I would shorten the fuel line if it were me just so's I didn't have all the extra line cluttering back there...

Boaters typically find that loading everything in the transom area is a mistake. Makes it harder to get and stay on plane. Sometimes causes "porpoising" too plus the transom often sits so low that it is a swamping hazard. A 5 ft fuel line is not long, just coil it up a little to keep the slack from being in the way. Setting the fuel tank on the pumps is probably a mistake too, lots of pressure on those plastic items plus it could wear a hole in the tank. Most people never have batteries wear down except for a trolling motor. Fishfinders, stereos, spotlights (rarely used), running lights, bilge pumps do not draw much current at all.
