This carburetor fits all of the Mercury 6HP 4-stroke outboard engines 1999 and newer. This includes outboards with serial numbers 0R000001 and higher.
This is a 6hp jetted carburetor - be cautious of other companies selling a carburetor for 4, 5 and 6hp outboards - these are usually just 4hp carburetors and, although the outboard will run, you will lose power.
If you are upgrading a 4hp Mercury to a 6hp, we recommend our 4hp to 6hp Upgrade Kit that includes both this carburetor and the correct propeller to use in order to take advantage of the additional power.
If you are upgrading a 5hp Mercury to a 6hp, this carburetor is all you will need as the 5hp comes with the higher pitch propeller already.
We stock all of our products and ship quickly (usually either the same day or next business day) from Massachusetts.
