The Zinc/Propeller Locking Nut Assembly is proprietary to the Rollexx. The zinc protects the motor shaft and internals and is a very important routine maintenance item! You should keep 1 or 2 in stock for your diver to access when needed.
The Rollexx Zinc/Propeller Locking Nut Assembly is constructed of a stainless steel threaded core with 99% pure zinc making up the balance of the 1-5/8″ dia x 2-1/8″ long assembly plus a 7/8″ hex nut and center lock set screw.
To order spares simply call or email with credit card info, we will get the zinc right out to you!
