I was watching the Deadliest Catch and some of them are fishing near the coast of Louisiana in the off season. I noticed that one of their much smaller boats was running four Mercury outboards marked 350. I looked them up and was shocked to see that they’re 2.6 liter 350 hp supercharged 24 valve inline sixes that weigh 668 pounds each! Seems unreal to me that a smallish boat can handle over 2,600 pounds hanging off the transom with a combined 1,400 hp.
