Probably dead already. The duct tape around his head is a pretty good clue on that. And, that is possibly the only way to keep the feet still while the concert sets.
The only reason he came up is that the bucket was way too small. 5 gallon bucket is just not enough weight. Need a washtub, 20 gallons or so. Actually, one of the problems is that there should be about 200 lbs of concrete and the body itself is another 200 or so. That is a lot of weight to throw over the side of a boat.
