Review on Stainless Lock Out Indexing Plunger Without Industrial Power & Hand Tools by Jonathan Unruh

This was recommended as a replacement for the screw plunger that allows the ski pole to stay in the raised position on the back of our 2004 GTX Seadoo Wake handlebar. I would recommend some LocTite to keep it from coming loose during use. Fits perfectly! You have to buy this. The black handle acts like a piston.
