This carburetor upgrades the Mercury 9.9HP (1999-2004) 4-stroke outboard engines to 15hp.  Fits both standard and Bigfoot models.  No modifications are necessary except for, in some cases, needing to swap out the choke linkage from your old carburetor.  Instructions are included on how to do this and it only takes a few minutes.

If your outboard is newer than 2004, please see this carburetor:  Mercury 9.9HP (2005 and Newer) 4-Stroke Outboard Carburetor
