Ever seen drifting in a race boat?? Ride along through the lens of onboard cameras.You'll see team Unpredictable do their best impression of drifting in a race boat at around 2:25. These boats are capable of over 100+ mph,Running in less than 6 inches of water at times. The race boat will drift from one side of te river completely across to the other side.
Jet Boat Racing... Guaranteed Satisfaction!
See what up to 1000 horsepower sounds like from
these whitewater jetboats with their motors blasting through your systems
speakers. Nothing like good old fashion roaring engines. Don't try this at
home. Professional drivers on a closed course.
Not All Boats Are Created Equal!!!!!!!

Introduction to Whitewater Jet Boat Racing...
Visit us on the web:
A breif explanation of the sport:
Eagle is the number one race hull but there are others racing. Kwikraft is
a New Zealand hull designed and built by Tony Ward, 19 to 21 foot tunnel.
There also is at least one Doug Riddle hull still racing and there are
several unique one-offs, the two built by River Wild are good examples. One
is a 21 foot B-class tunnel and the other is an 18 foot FX class tunnel.
Bottoms are anywhere from .160 to 3/16ths. Sometimes AR plating is used as
an extra layer of protection. Sides are generally .090, decks can be even
less than that. Saving weight is very important and the location of the
weight in the boat is even more important. Most use spoons, an add on piece
in front of the intake. Hulls are generally tunnels although v-hulls have
done well in FX class, and River Wild has built two super light "semi-wing
in ground effect" hulls that are also quite good. The FX version did
especially good in 2001. I believe the Eagle 19 foot Sport step-tech will
become a big force in FX class in the next few years.
Since these boats are raced through whitewater interspersed with rocks and
logs, they need to have fairly precise handling characteristics compared to
other types of race boats. They also need to be very predictable. Bad
habits and quirks can put you up in the rocks or worse.
The pumps are obvously highly modified, but based on Berkeley, Legend,
Aggressor or American Turbine production pumps. Stainless impellers are
almost universal. Full rock grates, although again highly modified, are
also universal. On the higher powered boats much attention is applied to
supplying the thrust bearing with lots of clean lube. Various methods are
used for this including pumps and pressure lube systems. Fabricated steel
nozzles are used almost exclusively, and various combinations of wedges.
The nozzle replaces the entire piece from the bowl back. It's probably
obvious, but maybe it needs stating, the black art of this racing is the
pumps and the hulls.
The engines are pretty straight forward. They have to make good horsepower and torque at
less than about 6500 rpm, but they have to be able to do this fully loaded
down at full throttle for up to 30 minutes. They have to be able to do this
reliably at least twice a day (sometimes more) and for two days in a row.
That's the minimum requirement to finish and you know the saying, "to
finish first, first you have to finish". Rumour has it, and it's only
rumour that I've heard, that some of the unlimited engines are over 650
Engines and pumps are set way back, most of the pump hangs out the back of
the boat. Fuel tanks sizes range from 25 to 35 gallons for an FX boat to 60
to 100 gallons for an Unlimited boat. Usually they are set up as saddle
tanks, at the very back of the hull.
Most boats have run rollbars in the past and it is now a requirement. Most
are made out of aluminum and have double or triple hoops with back braces.
Perhaps we may see a move towards chrome moly construction as the anchoring
and hoop requirements begin to make them a good tradeoff weightwise. Five
point harnesses with lever locks are also a requirement, not to mention a
good idea. Race type lifejackets from Lifeline and Security are also used
as are fire suits.
All boats carry first aid kits, fire extinguishers, two ropes, paddles,
tools, some minor spares and a red flag.
SJX Jet Boats Unleashed "You gotta see this!" Vol. 1
A collection of videos and pictures from factory R&D testing in Idaho to
fishing and hunting in Alaska. These are just informational videos of what
we do in our SJX Jet Boats. (Video 1 of 4) (Not intended for marketing or

wankel turbo ski race boat
owner has opined, boat is going 105 here but has done 118! That's pretty
fast in a boat that size, especially with the chine walk it's doing.
Driving this would be like laying a 2x4 across a bowling ball and trying to
balance yourself, on ice!!! And people waterski behind these too!!!
Rinspeed Splash: Sports Car & Speed Boat
Another remarkable concept from Rinspeed that turns a sexy sports car into
a sexy amphibious vehicle. You'll love this video, it has everything,
The Rinspeed "Splash" is the true incarnation of a really cool and fun
sports toy. At the push of a button a cleverly thought-out hydraulic
mechanism transforms the sports car into an amphibious vehicle. But that
alone wasn't enough for Frank M. Rinderknecht founder and boss of Rinspeed.
A highly complex integrated hydrofoil system enables the "Splash" to 'fly'
at an altitude of about 60 cm above the water.
Crazy Capizzi on his home made jet boat "Jet Jon"
Hey, my friends call me Crazy Capizzi. This is what you get when you cross
a john boat with a jet ski! Too Fast! This is a $300 97 tighr shark jet ski
motor and a $25 12' aluminum boat. it probably did about 40mph in about 2
seconds. I built it in one weekend. Unfortunately once it got up to top
speed it would make a hard turn. I think it needed the jet to face up more.
