This style carb is used on Seadoo, Yamaha, Kawasaki, Polaris, Tigershark, Mastercraft (yes they made some PWCs), and probably nearly all PWCs out there aside from the few that used Keihin carbs.

These carbs are a little different than most, and it is imperative to the enjoyment of your PWC to have them dialed in just right.
Here is my process of disassembling, cleaning and getting them ready for tuning on the water.
