I giggle when we have these threads, as one of the biggest reasons most of us love these boats is the shallow draft compared to a prop boat. And then as soon as we see these clips or ask questions about running in less than 3ft of water, so many cry wolf and say don't do it.
When you look at the video above, understand where that water is being sucked through, the jet pump. And then look at your pump and look at the screen where water is actually taken into the engine. Yes, some sand is going to go in, yes over time it can cause damage, and yes, and outboard motor is no different. These engines can take it.
Would I continuously run in less than 3ft of water, yes if it gets me to where I need to. Should you run in less than 18" no, but for a shot to pull me out of a situation yes. The channel into my private bay is 1.7ft of water below the hull. I idle through that channel multiple times/week. I would bet by the end of the summer, I may be running that 50ft channel on plane. I know the bottom and where the dangers are.
So pick your poison, brag about your shallow draft, or pat yourself on the back for protecting your jet pumps, but in the end, we are no better than an outboard when it comes right down to it for this particular situation. (other differences still valid)
