I have a 2002 Merc 150 EFI Saltwater series with the number OT587917 on a sticker on the powerhead. I don’t find this listed as a serial number on some parts lists. Can you tell me if this is, in fact, a valid serial number for this motor so I can order parts for it?

That is a good serial number. You can go the the Mercury Marine web site and look up parts with the serial number.
