Thanks folks. I do have the owners manual that is Grady overall, with a section in the back of the binder for the Marlin.
Section 6-6 and 6-9 discusses the fuel tanks, to include a schematic of the tanks; but I am curious of a full schematic of the Marlin below deck, including locations the fuel tanks, fresh and gret water tanks, drain lines, etc.
If anyone has the between hull schematics it would be much appreciated.
Safe boating and tight lines.
