Prop Nut Zinc for 1-1/4" Shaft

Part #: Z4023

Propeller shaft nut zinc for boats with a 1-1/4" diameter shaft and a fiberglass skeg molded as an integral part of the hull as opposed to separate bronze strut. The skeg design does not allow use of a more traditional clamp-on shaft zinc.

Nut style design allows for use on boats that do not have a traditional strut with room forward for mounting a donut style zinc.

Known usage:
• Catalina 375
• Catalina 380
• Catalina 387

For use in salt water.

• Thread: 7/8"-9 (this is the thread machined onto the aft end of a 1-1/4" diameter prop shaft)

This zinc nut can be used on any 1-1/4" diameter shaft, but may require that an additional hole be drilled in the shaft to pin the nut.
