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

bobby eddings :

you should see a topfuel hydro.

ulysseessylu :

cavitation...

Poor fish

J✌️🇦🇺 :

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

Radouane les Angles :

🦆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😁👍

Chris Grasser :

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

Black Rifle Transportation :

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

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

mattyb :

how do think a turbine helicopter works?

Dave's Adventures :

The turnine engine is probably driving the propeller.

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

Jon Moore :

no one see the hull sitting on a step?

SR_Asteroid :

That’s a damn f1

JustinCase2A :

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

BA313 :

dead Internet theory right here

Kingsofnobody :

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

andrea :

vortex current

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.

Anthony :

The jet engine turns the prop

rattler546 :

Without the prop it would get airborne easily

Put God First :

Ai

ak.pilot :

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