Quicksilver 806031A2 Bell Housing Assembly MerCruiser Alpha I Gen II Sterndrive

The Quicksilver 806031A2 is a genuine OEM bell housing assembly designed for the MerCruiser Alpha I Generation II sterndrive system. The bell housing serves as the critical structural interface — the helmet-shaped housing to which the sterndrive unit bolts directly to the transom assembly, sealing and connecting the drive to the boat's hull.

This is a direct factory replacement for the original Mercury Marine part number 816459A1, ensuring proper fit and function without modification. It is engineered specifically for the Alpha I Gen II platform introduced in 1991 and is not interchangeable with earlier Alpha One (Gen I) components.

Key Features:

• Genuine Quicksilver OEM factory part — not aftermarket
• Direct replacement for MerCruiser Alpha I Gen II sterndrive bell housing
• Supersedes original Mercury Marine part number 816459A1
• Designed for Alpha I Gen II drives from 1991 to present
• Sterndrive-to-bell housing connection torque spec: 50 lb-ft (68 N·m)
• Precision-engineered fit for correct alignment of gimbal bearing and engine coupler

Replacement of the bell housing is typically required when the housing has corroded through or sustained physical impact damage. Important: Alpha One and Alpha One Gen II bell housings are not interchangeable — always verify your exact drive generation before ordering. Confirm fitment using your MerCruiser serial number.
