I'll second that too , the amount of people that i see setting the engine up on muffs then drop the boat in the water to only have problems
At least with a tub of water it gives a bit of back pressure on the exhaust if setting up the tickover,
Once blew the bottom out of a plastic dustbin/garbage can when trying to start an engine after flooding the carb ,,, fuel must have gone down into the exhaust when it back fired the explosion shot the engine about 3 ft high and blew the side and bottom out of the drum ,, engine ran great after that but we all had wet feet lol
