Prop Nut Zinc for 1-1/4" Shaft

Part #: Z4023
$59.18
Propeller shaft nut zinc for boats with a 1-1/4" diameter shaft. Boats with traditional bronze struts may use this zinc or the more familiar zinc collar pictured below under "May we also suggest". If the shaft in your boat is equipped with a cutlass bearing mounted directly into a fiberglass skeg molded in as an integral part of the hull, then this type of aft mounted zinc is a requirement.

The skeg design does not allow use of a more traditional clamp-on shaft collar 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
• Catalina 400
• Catalina 42
• Catalina 440
• Catalina 5 series boats equipped with 1-1/4" shafts

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.
