I'm running an older Bayliner 2070--1984 I believe. Just my second summer with her, and I'm trying to figure a better way to haul extra fuel to extend my range. She's got a single carburetor Volvo four cylinder and a 40 gallon aluminum tank under the deck. I usually carry 20 extra in jerry cans. I hate having the darn jerry cans in the way on deck, especially after I've emptied them! And twenty extra gallons still doesn't get me the range I'd like sometimes. Any suggestion for carrying extra fuel in some sort of collapsible container? Or maybe fitting some auxiliary tanks under deck? Looking for ideas! THANKS!
