OK MJ and Hammer...here's lookin' at port-side tank/filler-hose and filler-cap...sorry this ol' girl's so dirty ::) ...
Here's a shot from bow...
And here's a side shot...
The size of the box was driven by the size of the 40 gal tanks in each, but if anybody wants dimensions, I'll get 'em...even if it had a belly-tank, these boxes woulda been great storage...got the idea from a buddy's Robalo 2160 ;) ...an added bonus to these boxes was a place to put ROD-HOLDERS... ;D ...ready access from the cockpit ;) ...
