Take a look at the Testimonials posted below. We know our products
offer you - the Jetboat Enthusiast - exceptional value and performance. |

| The 8.5” Scott Jet added 8 mph to our top end and it went
from 39 mph to 47 mph. The high pressure that this pump puts out allows
us to adjust our trim to work within a load: our boat at full load
will weigh over 10,000 pounds. The RPM range with the old 212 Hamilton
Jet with 4 kW impeller ran from 3400 rpm to 3950 max rpm. The
new Scott Pump allows us to run from 3200 rpm to 5000 rpm. The
amazing thing about this system is that if you don't want the RPM that
high you can simply change the nozzle tip with three screws and the
RPM will increase or decrease 200 rpm per tip size. We have our nozzle
set for cruise, not speed, so it will max out at 4700 rpm. If you somehow
managed to damage the impellers you can simply insert another nozzle
of a smaller diameter, and it will work like a new impeller. THIS PUMP
KICKS ASS !! |

We tested a 24’ Wooldridge with a new
8.5 inch Scott pump dual stage. The boat picked up an extra 750 rpm:
it went from 3950 rpm to 5000 rpm. We changed the adjustable nozzle tip
from 118 to 112, which takes about 10 minutes, and dropped to 4700 rpm,
which gave us an extra 8 mph, on the GPS, over our 212 in the same boat.
It gave us great midrange punch and made the boat handle better empty
and loaded than it had in the last 420 hours that we have used it.
The
nozzle allowed the boat to lift out of the water with a 10,000-pound
payload easily, whereas a 212 with a 4 kW Turbo impeller would struggle
for approximately 250 feet before it would pick up the same load. There
was no bow steer using the Scott Pump with the adjustable trim, as there
was with the 212 when making sharp turns. We also saw approximately a
12% decrease in fuel consumption. With this jet, we now have full use
of our 425 hp.
Before,
with the 212, we were only making use of about 350 hp, due to not getting
our full rpm. Thanks to Scott Pumps, we now have a truly great boat! |

Tested: 17-½ foot Omineca Puddle
Jumper with an Optimax 200 2 Stroke Sport Jet against a Kodiak V-6
230 hp 8-inch single stage Scott Pump. These boats were built the same
in order to make the tests as fair as possible.Note: we are still working with the impeller size and feel that with
our next test we will see even more improvements with the Scott Pump.
That being said, even with what we think is the best impeller, it matched
or beat everything on the Optimax 200 setup.
- No comparison with both boats in reverse. The Scott Pump works
great. Sport Jet needs to be pushed off the shore.
- More top and at flat-out speed.
- Same hole shot when both boats are empty.
- When both boats are loaded, Scott Pump has way better load lifting
and hole shot.
- Equal fuel consumption, but if you take into account the oil consumption
on the 200, the V-6 is cheaper to operate.
- Regarding the life of the two boats: the V-6 should be considerably
longer due to the four-stroke engine, versus a two-stroke engine.
- It is quieter, when idling and no smoke with start up, and quieter
with half and full throttle.
- Better turning and handling than the Sport Jet.
- And did we mention how nice it is to have the heat in the late
fall?
It is a heavier built jet pump and when the impeller gets worn down you
can change the nozzle tip and get your performance back, and then repair
your impeller at a later date. |

"Initial trials of
the new SDM jet unit have shown it to be an exciting and dynamic
unit with increased pick up and performance right over rev range.
We have been able to improve the speed of our boats by more than
20% up to 55 knots using the new SDM unit, making Konrad Scott's
new SDM jet unit an awesome option for those wanting a high performance
boat powered by jet technology"

"Using a Scott Trim
Nozzle with a 1500lb pay load we were able to drop our planing speed
2-3 miles per hour and achieved 2-3 miles per hour top speed increase.
Our second test was
with an ATV on the rear of the boat (approx. 2200lb payload). Without
the trim nozzle the boat would only plane when we went into shallow
water, after it wouldn't lift the load in deep water - the boat also
porpoised very bad. But with the trim nozzle in deep water it took
approx 70' to 80' to reach plane and ran nice and flat with no porpoising,
also the handling was much better." |

The boat tested is
a Wooldridge Sport Tour Extra Wide with a 425 HP Motor and a 212
Hamilton Jet.
"After owning this boat for 4 years and
400 hours of operation, we feel the trim nozzle made the boat a much
better driving, handling and performance boat with an approx 1 1/2 to
2 MPH gain from our test results but feel that if the tests could have
been done on the same day it would have shown a 3 to 4 MPH gain." |

| Please Note -
The water temperature on May 9th 2006 for the stock planing test was
50 degrees. The water temp on May 18th for the Trim Nozzle tests was
62 degrees. Also - the intake stomp grate on the May 18th test was hanging
down approx 1 1/2" at the rear. |
