Product Details

The Quicksilver 90185A1 Skeg Kit (G/H) is an OEM replacement skeg designed specifically for the MerCruiser Alpha One Gen II sterndrive. The skeg is the fin-like projection at the bottom of the lower unit that protects the propeller and gearcase, improves directional stability, and is one of the most vulnerable components on any sterndrive — prone to damage from underwater obstacles, shallow water, or accidental grounding.

This genuine Quicksilver/Mercury Marine part restores the lower unit to factory specifications, ensuring proper hydrodynamic performance and continued protection for the drive's internal components.

Key Features:

  • Genuine OEM Quicksilver/Mercury Marine replacement skeg
  • Designed for MerCruiser Alpha One Gen II sterndrives
  • Compatible with drives bearing serial number 0D469859 and above
  • Restores factory form, fit, and function to the lower unit
  • Part designation: Skeg Kit — G/H (Q=T)

Important Installation Note: This replacement skeg requires professional welding for installation and must be installed by a certified welder. This is not a bolt-on replacement.

Compatibility Note: This skeg is designed exclusively for the Alpha One Gen II and will not fit the original Alpha One drives. Always verify fitment using your drive serial number before ordering.
