@throttletok0: That jet really does add to the effect though🔥 #jetboat #fastboat #boating #racing #DidYouKnow

Tybo :

The jet engine does absolutely nothing for thrust. It provides the power to the shaft.

bobby eddings :

you should see a topfuel hydro.

ulysseessylu :

cavitation...

FLHTK :

Props don’t push water, they create a pressure differential between the front and back of the blades that creates lift. Those bubbles are act the water boiling from being in a vacuum state. If you want to learn more about boat props get on YouTube and look up “propeller physics every boat owner should know”. It’s an extremely informative video

J✌️🇦🇺 :

thats a turboshaft motor engine like a helicopter connected to the prop very cool and quite loud

Black Rifle Transportation :

You realize the jet is what’s driving the prop right?

Chris Grasser :

the propeller is doing all the work. the "jet" engine is not producing thrust at. all. that is only exhaust.

🦆EvilMaple57🦆 :

so, the turbine engine is used because of its extremely high torque and rpms over a normal combustion engine hence why they're used in tanks like the M1 Abrams and in boats like these. Also, Chrysler made a car at one point that was turbine driven and could run on al.ost any oil from kerosene to old fry okl😁👍

dead Internet theory right here

macabemooney :

so I have a friend who used to be on the pit crew of the hydroplane boats. and I am going to inform everybody here that the propeller is the only thing that is propelling that boat forward that big exhaust vent that's hanging out the back of the boat, is just that exhaust from the turbine now what most people don't know is that turbine is in there what we would think of as backwards. the front of the turbine is facing aft because it is that shaft that is connected to the transmission which is connected to the prop. the turbine is not producing thrust as you would think of in a plane. because that is a gas turbine not a jet turbine. there is a difference a gas turbine which is what you would see on a turboprop airplane or a turbo engine helicopter does not create using exhaust thrust it creates using shaft horsepower. unlike a jet turbine which creates thrust from the exhaust... like on a Boeing or Airbus aircraft

Poor fish

Kingsofnobody :

The jet is the exhaust for the motor. That’s how helicopters work. It’s a turbine engine used to create mechanical movement.

rattler546 :

Without the prop it would get airborne easily

Dave's Adventures :

The turnine engine is probably driving the propeller.

JustinCase2A :

That looked like the Tri-Cities, WA. The Columbia Cup.

ak.pilot :

I thought bubbles around the prop was considered turbulent and considered less effective?

TitaniumSkullTV :

cleaver prop, slips like shit all the time but less so when partially surfaced. the jet engine isnt providing any thrust at all. its a helicopter turbine with an output shaft to turn the propeller.

Jon Moore :

no one see the hull sitting on a step?

Anthony :

The jet engine turns the prop
