Best to search by serial # to get the correct oem parts. It should be on top of your flame arrestor. If serial number is worn off it is riveted on a tag next to the starter. If tag isn't there the block has likely been swapped.

Otherwise most those alternators have a sticker on them with the merc PN and original manuf PN.

I like www.mercruiserparts.com as an initial go to as well.

Try marineengine.com and you can also search there by your engine serial number.
