I have a stainless portable outboard motor test tank. Used to purge my Yamaha 30 HP outboard with a 20" leg. My Yamaha weighs 130 Lbs. Built with dual water in ports with shut-off. One for the feed hose directly and one with an additional black feed hose to keep water in circulation when using. From the bottom of the tank to the wooden transom is 36". Put in a bottom drain which can be drained where you are or hook a hose to re-direct water. Legs are 2x6 and center frame 2x6 with with aluminum base plate is lag bolted together. Tank interior - 30 L x 18" D x 18 wide ( at the bottom ). Whole thing can be easily transported.
