Mercury to Sierra Marine Parts Cross Reference

A Mercury-to-Sierra cross reference converts a Mercury Marine part number into a Sierra aftermarket number. Look up the Mercury number in the table on this page, then search CLR Marine by the Sierra number (or the Mercury number) to open the current listing.

How do you convert a Mercury part number to Sierra?

Find the Mercury Marine row that matches the printed number, read the Sierra number in that row, and search that Sierra number on this site. Compare the product title, SKU, and photo before ordering.

• Enter the Mercury number exactly as stamped or printed.
• If the table lists more than one Sierra match, open each listing and compare the described application.

What is a Mercury to Sierra cross reference?

It is a number map: Mercury OEM identifier → Sierra replacement identifier. It does not replace a product-page check. Superceded Mercury numbers and kit vs single-part listings can differ from the original engine tag.

Should you search Mercury numbers or Sierra numbers first?

Start with the Mercury number if that is what is on the engine or old box. After the table returns a Sierra number, search the Sierra number — that is usually how aftermarket listings are titled. Keep the Mercury number handy if the listing also shows OEM interchange text.

Why does the same Mercury number appear more than once?

One Mercury number can map to more than one Sierra number when Sierra splits applications, supersedes a part, or lists a related service item. Open every matched listing and compare the SKU line. Do not pick the first row only.

Where do you confirm the live listing after a table match?

Confirm on the CLR Marine product page: title, SKU, MPN, image, and any listed application. Use onsite search or live chat if the Mercury stamp is incomplete.
