Boat Water Tanks

Did you know water weighs 8 pounds per gallon, or 1 kilogram per liter? In other words, water tanks are very heavy when full. For this reason, mount your boat water tanks low in your watercraft or RV. Great Lakes Skipper has rugged boat water tanks in a range of sizes, from 4 gallon on up, in materials like polyethylene and aluminum. We add thousands of boat parts and accessories to our huge inventory every month, so check back frequently for the latest and greatest discount deals on boat water tanks from Great Lakes Skipper.
