Lucky 13 Pump Cone – Kawasaki

Description

All billet construction and hard anodized to prevent corrosion. Easily
adjusted by removing stainless steel tail cone bolt, pulling off billet cone
and adding or removing supplied spacers. The cone comes with a 3mm, 4mm and
5mm spacer. Spacers of different thicknesses are available for purchase
separately.

The extended length of the Lucky 13 Performance Pump Cone allows for custom
pump pressure tuning resulting in additional thrust allowing the ski to reach
higher top speeds, achieve better acceleration and have reduced cavitation.

Using this cone will result in initial lower RPM’s therefore it’s important to
use a larger exit diameter on your venturi nozzle than you would normally run.
Typically you will want a 3mm larger exit nozzle than you would run without
the adjustable pump cone. BBest results will be achieved when boring out your
OEM nozzle to a larger size.

Utilize spacers to ‘dial in’ your RPM and find the ‘sweet spot for your ski.
Testing different spacer arrangements along with exit nozzle diameters in
order to dial in your RPM’s will result in gains from holeshot, midrange
acceleration and also top speed. In some cases it may also be necessary to
depitch the trailing edge of your impeller slightly to achieve desired RPM’s.
Best results are generally achieved when spacing the cone back into the
venturi as far as possible and then adjusting venturi nozzle diameter and
impeller pitch to achieve desired RPM. It’s important to note that each ski
will vary. It’s important for you to test different configurations to see what
works best with your ski’s setup. When you put forth the effort to dial this
system in you will be rewarded with substantial gains.
