Product Details

The Sierra 18-72005 Nut and Washer Kit is a marine-grade propeller hardware kit designed for MerCruiser R, MR, Alpha, and Alpha Gen II stern drives. This kit provides the essential fastening hardware needed to properly secure a propeller to the prop shaft, helping maintain safe, reliable operation on the water.

Key Features:

  • Includes propeller nut and tab locking washer for complete prop shaft hardware replacement
  • Designed to meet or exceed OEM fit and function for MerCruiser stern drive applications
  • Tab washer locks the prop nut in place, preventing vibration-induced loosening during operation
  • Manufactured by Sierra International, a trusted leader in marine aftermarket parts
  • Ideal for use during propeller replacement or routine lower unit inspection and maintenance

Replacing the prop nut and tab washer during any propeller service is a recommended best practice. Worn or bent tabs on a used locking washer can allow the prop nut to back off, potentially causing propeller loss or damage to the prop shaft. Sierra's 18-72005 kit ensures a fresh, secure installation every time.
