Switching to our Stubby Freestyle Pump Cone will allow your engine to rev noticeably faster and in return thrust your ski further in the air.
When trying to gain performance, every little thing matters. So when it comes to the low end performance, a simple pump cone is a must!
Anodized black and includes marine grade hardware.
PLEASE NOTE - *Does not fit all Yamaha 4-stroke applications. Find the 2-stroke stubby pump cone here.
