Prop Shaft Anode – Streamlined shaft collars provide cathodic guard for propeller shafts with Mil Spec anode for a tight fit to the shaft.
These zinc prop shaft anodes are high quality pressure die-cast and provide effective and inexpensive protection for your boat in salt and brackish water. Two stainless steel slot-head screws with lock washer and hex nut are used to lock the anode halves around the shaft. The stainless steel hex nut is pressed into the anode body.
