Now that's what you call reversing buckets!

[Britboater]

I don't think there's cables attached to these , or Thrust vectors needed .

Wow....that thing is moving some serious water in neutral/reverse!

 

[Mark]

First off... Wow! What comes to mind is I never have that much help, if I have that many people watching me with cameras it's because they are laughing at me trying the same thing! And I feel like when I try that I never have that much room! Haha! And do you think he is using a twin engine lateral thruster or two single thrusters @JetBoatPilot ? Also did he get his thrusters early because he is stupid rich? Lol!

 

[JetBoatPilot]

Wow, that would be a monstrous set of LT's!

 

[Britboater]

You can see around 3mins he has some sort of thrust vectoring as the water is directly at 90 degrees to the boat.

Never imagined a giant yacht like that would have jet drives.

I had to look it up, looks like it has twin Kamewa jets (71SIII to be exact), which is owned by Rolls Royce. Page 4 in the below document is what this 151' yacht has,

Ugh, I should be working, but this is more interesting right now...
