Before Ordering

How to Confirm MerCruiser Part Fitment

Mercury MerCruiser parts should be matched by serial number, drive type, engine model, and existing part number whenever possible.

Use Engine Serial Number

Many MerCruiser parts change by engine serial number range. Model name alone may not be enough.

Confirm Drive Serial Number

Alpha, Bravo, and other drive components should be confirmed using the sterndrive serial number when possible.

Check Old Part Number

Compare the stamped, printed, or listed number on the existing part, box, invoice, or service record.

Watch for Supersessions

Mercury and Quicksilver numbers may supersede to newer parts, kits, or updated service components.

Important Installation & Safety Notice

Installation and service must be performed by qualified, authorized personnel only and in accordance with OEM procedures. Improper installation, misuse, incorrect application, or unauthorized repair may result in equipment failure, property damage, serious injury, or death. Marisol Marine assumes no liability for damage, loss, or injury arising from improper installation, incorrect application, or unauthorized service.
