Product Details

The Sierra 18-21006 is a non-greasable gimbal bearing designed for MerCruiser sterndrive applications. This critical component supports the drive shaft and allows smooth rotation while absorbing thrust loads during operation.

Key Features:

  • Non-greasable sealed bearing design for reduced maintenance
  • Precision-manufactured to OEM specifications for reliable performance
  • Engineered to withstand harsh marine environments
  • Direct replacement for MerCruiser part number 30-862540A3

Compatibility:

  • MerCruiser Gen II drives (1998-2010)
  • MerCruiser Bravo I, II, and III drives (1996-2010)
  • MerCruiser X, XR, and XZ drives (1996-2010)

The gimbal bearing is a wear item that should be inspected regularly and replaced during transom assembly service or when excessive play is detected. Proper installation requires specialized marine tools and knowledge of sterndrive systems.

so far so good

cool

Quick and easy!

You seem to have the best price and your pictures help a lot. HOWEVER -- no place did my order say "Mercury Grand Marquis 2003 *Passenger Side* Glass -- and that has me concerned because I have to go by make/model/yr and then picture alone!

The prices were so much better with Autoplicity I couldn't believe it was the same item. E-mail response came within an hours. Will buy from again.<br><br>Ok, the verdict's still out on this one. Autoplicity said my item was shipped two days ago (two days after ordered), but FEDEX indicates they've only received "shipment information", after four days. I'll follow up when I actually see the order.

The item was what i was looking for and the price was right. Item was very good quality. Would order from Autoplicity again.

Best prison the Internet and quick order fulfillment. Glad to have found Autoplicity!
