This skeg knob fits early Wilderness Systems Tempests RM (plastic) 2004-2010 and (glass) Tempest Pro 2004-2012 (Does not include the set screw, needs a 10x32x0.5" Flat Head machine screw preferably brass or 2nd choice stainless steel) on these kayaks a stainless steel slider tube runs through the knob and the steel skeg cable is inside this stainless steel tube. The main reason to replace control knob is because you need to replace a bent skeg cable and found that the setscrew in the knob is frozen in place due to corrosion so the knob has to be cut to pieces to get the system apart. We recommend a cut-off tool for this. Dremel makes an abrasive cut-off wheel (about 1.25" dia.) accessory that will do the job but you will likely break a couple of the abrasive disks so be sure to have several disks on hand. A specialty cut-off tool with a 3" diameter abrasive disk will make this a faster job (15 minutes vs. an hour). Such cut-off tools are available from Harbor Freight Tools. Before assembling, remove the setscrew from the knob and coat it with an anti-seize lube so you'll never have to cut the knob off ever again. Automotive white grease works well for this. When assembling, if your skeg control system has the skeg cable inside a stiffener "Slider Tube", be sure the knob's setscrew is lined up with the hole in the Slider Tube, if you miss this hole you can bend the Slider Tube. When the set screw hits the steel skeg cable it should feel solid.
