Went with a friend for a boat ride ( he just got it back from the repair shop ) I smelled gas - raised the hatch and found gas pouring out of the lower screw holes on the Holley DP carbs. The idiots didn't tighten the screws and they fell out. ( they were laying on the intake manifold )
Had that happen to me when the sender mount on the top of the tank cracked. Gas was pouring out the top of the tank after I filled it up pooling in the bilge. Thankfully I was able to plug the leak, dumped about a gallon of liquid soap in the bilge and idled back to the marina.
