Product Details

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.

Great experience! Shipping was fast and the price was amazing. I'd actually wondered if it was too good to be true, but my ramps showed up today (exactly a week from when I placed my order) and they look great.

Execellent retailer. Easy to buy from online. Got product quickly at a great price. I highly recommend!

Mazda cargo mat for the CX-9 SUV came within 1 week. Mat fits perfectly; just as described. Autoplicity had the best price listed for this product; we are very pleased.

Fast and simple. Product delivered as described.

I ordered a chrome brake light cover from Autoplicity 3 days ago and received it today. Their add showed the piece I wanted clearly and it arrived today exactly as I expected. It looks great on my new Dodge truck. Thanks for the great service!

It was simple.

hard to find things but worth it

Easy shopping experience.

Great price on my Rampage rear bumper, good customer service, bit of a wait on the processing, but not horrible. After its all said and done, I'd shop here again.

quick and easy

Fast shipping and a great product at an unbelievable price! Thanks!
