Slide on Prop Protector for 1" shaft 80 mm diameter blade

7/8” BORE SLIDE-ON PROP PROTECTOR 80mm DIAMETER BLADE
 
Manufactured in one piece with a width of only 12mm, it is designed for installations where the gap between the propeller and the shaft bearing is small. A gap of 18mm is sufficient; this includes 6mm of space for water to circulate to the shaft bearing.  It simply slides onto the shaft after the propeller has been removed and is secured with a set screw that locates into a small drill dimple made in the shaft.
