Upgraded Strut for ProBoat Black Jack 24 v1 (pn# PRB08007). THIS WILL NOT WORK WITH THE STOCK ProBoat CABLE! We have designed a new strut with a few changes. - Added a replaceable, lead/teflon strut bushing. - Changed the strut to work with 3/16" prop (4.75mm) shafts. The stock strut is for 5mm shafts. - Increased the length of the knife edge on the front of the blade. - Included a bullet nose cone to reduce drag. Using this cable will will allow the use of the more common .150 cables with 3/16" prop shaft. Features: CNC machined billet aluminum construction and analyzed in silver. Includes: (1) OSE BlackJack 24 Strut for 3/16" prop shafts(1) Octura bushing, pn# OCT-oc6ltsb installed into the strut.
