Lucky 13 Pump Cone - 2014-2024 Yamaha Svho for Oem Pump - L13-YAM-SVHO

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. Best results will be achieved when boring your OEM nozzle out larger.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 will result in gains with hole-shot, mid-range acceleration and also top speed. In some cases it may also be necessary to reduce the pitch of the trailing edge of your impeller slightly to achieve desired RPM. 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. NOTE: For use with OEM SVHO pump only.
