Frequently Asked Questions

How many mounts do I need for my engine?

MerCruiser engines typically require two (2) rear engine mounts. This Sierra 18-2193 is sold individually, so you'll need to order two units for a complete replacement.

Can I replace just one mount, or should I replace both?

It's recommended to replace engine mounts in pairs to maintain proper engine balance and prevent uneven loading that could lead to premature failure of the remaining mount.

How often should engine mounts be replaced?

Engine mounts should be inspected annually and replaced when showing signs of deterioration, typically every 5-10 years depending on usage and operating conditions.

What tools are required for installation?

Installation requires engine removal equipment, press tools for mount installation/removal, and alignment tools. Professional installation is recommended due to the complexity of engine removal.

Will this mount fit my specific MerCruiser model?

This mount fits MerCruiser engines with Alpha and Bravo drives, specifically replacing part numbers 8M0103028, 99297A1, and others listed. Verify your part number for exact compatibility.
