Product Details

The Acme Automotive 6008 Nylock Prop Nut Kit is a complete propeller hardware kit designed for inboard ski, wakeboard, and surf boats with a 1-1/4" propeller shaft using the standard 7/8"-9 thread size. This kit includes all the hardware necessary when installing or replacing an inboard boat propeller.

Kit Contents:

  • Brass Nylock (nylon lock) nut — provides a secure, vibration-resistant lock on the prop shaft
  • Brass shaft key — secures the propeller to the shaft keyway
  • Stainless steel cotter pin — secondary retention for the nut assembly

Key Specifications:

  • Shaft size: 1-1/4"
  • Thread size: 7/8"-9 (standard)
  • Maximum torque: 35 ft-lbs
  • Nut and key material: Brass
  • Cotter pin material: Stainless steel

The propeller hardware components used to secure a propeller to the shaft are designed for limited reuse and should be replaced each time a propeller is removed. The brass nylock nut is preferred over a traditional castle nut, as its nylon insert provides a more reliable lock without sole dependence on a cotter pin.

Important Thread Note: There are two possible prop nut options for 1-1/4" shaft inboard boats. Some newer model boats may use a 3/4-10 thread instead of the standard 7/8"-9 thread. To verify, measure the overall diameter of your shaft threads on the prop end — if it measures approximately 0.875", this 7/8"-9 kit (6008) is correct. If it measures approximately 0.75", you will need a different kit.
