Made by Watercraft Werks this pole spring tensioner adds preload to the handlepole which reduces the handlepole weight 50%. The lighter handlepole reduces back, shoulder and arm fatigue. The stainless steel constructed shim installs in less than 5 minutes with basic tools. This handlepole spring tensioner is designed for the Kawasaki 759 sx sxi and sxi pro standup jet ski made from 1992-2002. This is a must have for all 750 sx sxi and sxi pro standup jet skis.
