Jet boat racing at Riggins Idaho,speed, and onboard footage in this video.
This was the 25th anniversary of this boat race. You'll be strapped into

All Motors No Music series 2 uncut racing
We threw out the music and let the motors with the deep V-8 engine sounds
to fill your eardrums to capacity. These high performance motors will make
music to your ears for the true motor head. We were only about 45 feet away
from them as the race boats going tearing by the camera. These race boats
are composed of aluminum tunnel hulls. There motors range from big block
and small block Chevys,Fords,and your ocassional T-58 gas turbine
helicopter engine. We would appreciate it if you left a comment and rating
on of motors only series! Thanks racing16

This is a winner ski boat that Mike Ivy at Ivy's Marine, in Flowood
Mississippi, completely rebuilt. He put a 2.5 Mercury race engine on it.
As you can see it is not only Fast but very stable.

A German-flagged container ship headed straight towards shore and
briefly ran aground in Hong Kong on Sunday afternoon (April 6, 2014).
The 192.5-meter-long Hansa Constitution was travelling along the busy
East Lamma shipping channel when it suddenly veered off course.
The Hong Kong Marine Department said the ship's main engine broke down.
People familiar with the shipping industry say the captain and Hong
Kong maritime authorities decided to the best course of action was to beach
the vessel to prevent it from colliding with other ships on the busy
The crew dropped anchor at the last minute, making loud screeching
noises, to slow Hansa Constitution as it headed straight towards the sea
wall outside the University of Hong Kong sports grounds in Pok Fu Lam.
The ship ground to a halt at around 15.22 local. It then slowly
reversed, as Marine, police and fire services rushed to the site. It was
eventually towed free. No one was injured.
The ship was travelling from Yokohama in Japan to Chiwan port in

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.
