Typical stage
1 mods at minimum recommended to the craft for this impeller-
Head mod,
D-Plate, ignition, etc.
Pre-impeller
mod info.-
Most people know that the Solas 13/19 Concord
is by far
the best performing impeller available for the GPR. The goal with
this many
enthusiasts is to retain similar rpm and acceleration as the 13/19,
but want
to obtain additional top speed over what the 13/19 already
provides.
This custom impeller is and feels virtually the same as the 13/19
in all aspects,
but produces a consistent 1-1.5 mph top speed increase.
Overall engine
rpm's come down approximately 70, with a minimum amount
of low end
snap reduction.
"New"
Custom Solas Concord 13/20 impeller- $239.99
* Comes with our Power-Tune
Stage 2 mod- Repitched, refinished and balanced to
our racer spec.
If you already
own a YF-CD 13/19 Solas Concord impeller, you can send it
in to our
facility to have it repitched to a 13/20, refinished and balanced
for
only $70.00.
While we will repair any slight damage with your current impeller
for this
price, major damage (like outside severe rock damage or outside
diameter
repair) will cost slightly more. Check our price list for more information.
Optional "Race" Finish- Add $20.00

Typical limited
and superstock mods or equivalent-
Cylinder
head mod, aftermarket pipe, carbs, ignition, etc.
Pre-impeller
mod info.-
With typical mods on the ski, but most importantly
the higher
rpm requirements of a Factory or Speedwerx pipe that were
tested, the
biggest goal was to be able to have an impeller that not only
allowed the
correct range of engine rpm, but naturally hooked up well off the
line, accelerates
well, while producing a competitive top speed. As most
people already
know when buying a Super Jet, the stock aluminum impeller
is not an
acceptable high performance option.
"New"
Custom Solas Concord impeller to match- $259.00
(Also available for $239.00, not relocated in the pump)
Produces a
huge acceleration increase, drastically reduces cavitation
throughout
the range and produced a top speed similar to our custom
Solas i impeller.
This modification has also been considered "the limited
legal magnum
pump" because of the way it keeps the pump loaded
throughout
the rough water and rides like you're on a rail. This custom
impeller
is by far the best performing impeller we've ever run on a Super
Jet or Wave
Blaster!
Limited pitch- 13/16, relocated in
the pump- with our recreation
finish and balance. Superstock-
contact us for a recommendation
based on
your engine set up.
Freestyle pitch- 13/15, relocated
in the pump- with our recreation
finish and balance.
* by relocating the impeller's position
in the pump, we are able to obtain
a very noticable "hook up" increase. We
also offer this service on any
aftermarket impeller you may already own
to maximize the performance.
- If you already have a Solas Concord
impeller, we can also modify it
to these specs for the following prices:
1) Power-Tune Stage 2 repitch, refinish
& balance- $70.00
2) Optional impeller relocating- $30.00
Optional "Race" Finish- Add $20.00
(Note:
price based on customer sending their undamaged impeller in to be modified.
Some
additional repair charges may be added if the impeller has previous damage.)
This application
is broken into two impeller options:
1) For an
ideal impeller for a stock or slightly modified 800.
2) For an
ideal impeller for typical limited and superstock mods
or equivalent-
Cylinder head mod, aftermarket pipe, carbs, ignition, etc.
Pre-impeller
mod info.-
The GP 800 is a craft that is known for
it's common
cavitating characteristics. The craft will spin the stock
impeller
on the low end while planing, and quite terribly in rougher
conditions.
While there are many designs of impellers available
that fit
into this pump, and some with decent improvement, The
Solas Concord
impeller is our choice for the ideal replacement.
This design
does the best job at reducing the cavititation problem,
accelerates
strong, and produces similar, if not better top speed
gains as
with a typical "speed prop" installed. We have been able
to take this
impeller and improve on it to provide even greater results
in the area
of "hook up" and top speed.
"New"
Custom Solas Concord impeller to match- $259.00
(Also available for $239.00, not relocated in the pump)
Produces a
huge acceleration increase, drastically reduces cavitation
throughout
the range and produced a top speed similar to our custom
top speed
impellers (common to get 1.5-2 mph. This custom impeller
is by far
the best performing impeller we've run on a GP 800.
For maximum
results, we highly recommend that you get the impeller relocated
by us- this
is the way we do it unless you specify not to have it machined back.
-Stock application pitch- 14/19, relocated
in the pump- with our recreation
finish and balance- $259.99, or $239.99
not relocated.
-Limited and superstock pitch- 15/20,
relocated in the pump-
with our recreation finish and balance-
$259.99, or $239.99 not relocated.

RETURN
The testing
for this custom impeller was done on a stock XL 800, and
slightly
modified XLT 800.
Pre-impeller
mod info.-
The XL/XLT 800 comes stock with an impeller
that spins
badly out of the hole, and in rougher water conditions. This
was out primary
goal- to find an impeller that would closely match the
stock impeller
at top speed, but hook up better, and reduce the spinning
as much as
possible. We were able to come up with a simple, inexpensive
way to not
only meet our goal, but find substantial water speed as well.
While there
is currently no aftermarket impeller available that produces
any positive
results, the Solas Concord is the design we found to give
us the best
starting point.
"New"
Custom Solas Concord 9/14 impeller
to match- $289.99
Results:
The 9/14 custom impeller produces a huge acceleration
increase,
(0-40 mph is much faster than the XLT 1200) drastically
reduces cavitation
throughout the range and produced a consistent
top speed
gain of 2.5-3 mph! A gain in water speed that we'd like to
point out
is very impressive and uncommon with a simple impeller change.
Typical top
speed of the very slightly modified XLT was 51.5 mph,
while producing
an average 54.7 mph (radared) with our impeller.
- If you already have a 10/16 YF-CD
Solas Concord impeller,
we can also modify it to these specs
for the following prices:
1) Power-Tune Stage 2 repitch, modify
the blades,
refinish &
balance- $100.00
Optional "Race" Finish- Add $20.00
(Note:
price based on customer sending their undamaged impeller in to be modified.
Some
additional repair charges may be added if the impeller has previous damage.)
Pre-impeller mod info.- In
stock or close to stock form, the RFI seems to
disappoint most people upon low speed
acceleration for towing and
general recreation. Enthusiasts in higher
elevation areas also require
an impeller mod to aid in reaching the
correct level of rpm's.
Impros O.E. impeller modification to match- from $50.00
Produces a
huge acceleration increase, great for towing skiers and
reaching
top speed faster. This was a tremendous gain at higher altitudes,
the craft
produced a much stronger performance increase overall.
At sea-level,
this particular mod reduced top speed by approximately 1.5 mph.
See our price list for additional services offered for your impeller.
(Note:
price based on customer sending their undamaged impeller in to be modified.
Some
additional repair charges may be added if the impeller has previous damage.)
Pre-impeller mod info.- With
the Coffman pipe installed, the stock impeller
does not allow the engine rpm's to reach
the target range in which the
pipe produces the maximum horsepower.
Impros
O.E.M. impeller modification to match- from
$50.00
(price
listed is for our Power-Tune Stage 1. A Stage 2 is also available for $70.00)
By having Impros modify the original impeller,
we are able to get the
maximum potential out of this common set
up. Gains you will see
include much better holeshot along with
a typical 2 mph top speed increase.
If the stock impeller is not available
to you anymore, we also offer a custom
Solas Concord in a 14/18 pitch that offers
the same rpm goals with
even better top speed. This impeller sells
through Impros for $240.00,
and comes with our Power-Tune Stage
2 features.
See our price list for additional services offered for your impeller.

Pre-impeller mod info.- Some
of the Pro 785's come with A NuJet made
impeller, while some come stock with a
Skat-Trak Swirl-type impeller;
either way, we find that replacing it
with our custom aftermarket Skat-Trak
Swirl impeller provides the greatest results
in the conditions this craft is
commonly used in. The OE Skat is geometrically
different from the aftermarket
Skat-Trak that we recommend. The OE impeller
has shorter "rock clearanced"
blades, which pulls it away from the pump
vanes, resulting in a less effective
pump "hook up".
Impros custom Skat-Trak Swirl impeller- $249.99
-Stock/limited application pitch- 10/18,
with our recreation
finish and balance.
-Superstock pitch- 10/19, with our
recreation finish and balance.
Results:
The custom Skat-Trak impeller produces quicker engine rpm,
which results
in a noticable acceleration increase for faster bouy-to-bouy
times, and
consistently produces more top speed (approx 1 mph on the
limited,
and 1-1.5 mph on a superstock) than the stock impeller.
*If you already have a Skat-Trak 12/17
or 13/18 Swirl impeller,
we can also modify it to these specs
for the following price:
1) Power-Tune Stage 2 repitch, refinish
& balance- $70.00
2) Optional "Race Finish" applied-
add $20.00
See our price list for additional services offered for your impeller.
(Note:
price based on customer sending their undamaged impeller in to be modified.
Some
additional repair charges may be added if the impeller has previous damage.)
'99-'04 Yamaha XLL/XLT 1200
A stock craft and slightly modified (head
mod, ride plate mod) was tested at
4000ft. and 6000 ft. above sea-level.
Pre-impeller
mod info.-
With the OE impeller, the craft struggles to accelerate,
and lugs
the rpm's far below the peak powerband. The overall performance
of the craft
is limited by the fact that the impeller was designed for sea-level
use only.
Impros O.E. impeller modification to match- $70.00
Produces a
huge acceleration increase, and allows the rpm's to reach the
ideal range
(approx. 6850). The overall performance of the craft, including
top speed
was drastically improved with this impeller modification. The XLL
performed
like we were at a sea-level lake.
Optional "Race" Finish- Add $20.00
(Note:
price based on customer sending their undamaged impeller in to be modified.
Some
additional repair charges may be added if the impeller has previous damage.)
'99-'04 Yamaha SUV 1200
A stock craft was tested at 4000ft.
and 6000 ft. above sea-level for this
test evaluation.
Pre-impeller
mod info.-
Like the XLL, with the OE impeller the craft struggles
to accelerate,
and lugs the rpm's far below the peak powerband. The overall
performance
of the craft is limited by the fact that the impeller was designed
for a sea-level
riding area.
Impros O.E. impeller modification to match- $70.00
Produces a
huge acceleration increase, and allows the rpm's to reach the
ideal range
(approx. 6850). The overall performance of the craft, including
top speed
was drastically improved with this impeller modification.
The SUV performed
like we were at a sea-level lake again.
Optional "Race" Finish- Add $20.00
(Note:
price based on customer sending their undamaged impeller in to be modified.
Some
additional repair charges may be added if the impeller has previous damage.)
'99-'04 Kawasaki Ultra 150
A stock and slightly modified craft (head
mod, Novi carbs) was tested at
4500ft. and 6500 ft. above sea-level for
this test evaluation.
Pre-impeller
mod info.-
With the OE impeller in stock form, the Ultra didn't
accelerate
very well at this altitude, and the rpm's were limited far below the
peak powerband
(approx. 6500). The overall performance
of the craft is limited
by the fact
that the impeller was designed for a sea-level riding area.
Impros O.E. impeller modification to match- $78.00
Produces a
huge acceleration increase, and allows the rpm's to reach the
ideal range
(approx. 6850). The overall performance of the craft, including
top speed
was drastically improved with this impeller modification.
With correct
pump shimming, the Ultra hooked up well and performed
fantastic
at these elevations.
(Note:
price based on customer sending their undamaged impeller in to be modified.
Some
additional repair charges may be added if the impeller has previous damage.)
'98-'00 Sea-Doo GTX RFI
This modification was tested on stock
machines, as well as slightly
modified RFI's, i.e. slightly higher compression,
carb work, etc. at
elevations of approximately 5500 ft. above
sea-level.
Pre-impeller mod info.- In
stock or close to stock form, the RFI seems to
disappoint most people upon low speed
acceleration for towing and
general recreation, especially at this
high elevation lake.
Impros O.E. impeller modification to match- from $50.00
Produces a
huge acceleration increase, great for towing skiers and
reaching
top speed faster. This was a tremendous gain at higher altitudes,
the craft
produced a much stronger performance increase overall. The
rpm's came
back up to around 6800 and the speed came back with it.
See our price list for additional services offered for your impeller.
