Ok , Ive read where you guys are putting you plugs in from the inside and the outside , Some are the theros bottle type rubber with the flip lever on them and some are screw in made of brass or nylon ( mine is the latter ) which go s in from the outside . I have stood on my head trying to fit the first type in that bung hole and with my (huge clubs I call hands) make it impossible to do from the inside . Dose anyone use the thermosbottle flip handle type on the outside ? If so wouldn't they fall out with stress of boating back there?
