4-Stroke Outboard Carburetor for Tohatsu 5 to 6HP Upgrade (1999 and Newer)
$209.99
This carburetor fits all of the Tohatsu 5HP 4-stroke outboard engines (1999 and newer) and converts them to 6hp. This is a simple carburetor swap, bolt-on conversion as the carburetor is the only difference between the 5hp and 6hp Tohatsu 4-strokes.
The models this carburetor works with include:
MFS5A2
MFS5B
MFS5BS
MFS5C
MFS5CS
MFS5D
MFS5DS
If you are upgrading a 4hp Tohatsu 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 (the 5hp outboards already come with this propeller).
