Fitment & installation
This listing is for the OptiMax/Pro XS air-compressor assembly pictured. Match your engine serial number, original compressor label, mounting, pulley and fittings before ordering. Pro XS horsepower alone does not confirm fitment, and this listing does not establish compatibility with FourStroke Pro XS engines.
Mercury catalogs use multiple 828123 revisions. 828123A28 is the identification for this used part; a similar T-suffix catalog number should not be assumed interchangeable without a serial-number lookup.
Photos show the actual assembly and its cosmetic condition. Check the engine service manual for installation, belt and air-system procedures. Mercury serial-number parts lookup.
