The housing is 95% identical. Float valve seat is smaller than mercury/quicksilver. The carb I received was stuck wide open. Had to completely pull it apart to fix the throttle. Then the choke didn’t work correctly. So I ended up putting this housing on with all my old mercury carb parts inside. All I needed was a new float valve but they are back ordered indefinitely. So this worked because the housing is correct but that’s about it. Internals were plastic. Not metal. Jury is still out on the jet size. I’ll update if it floods the motor at speed. Seems to be running very rich. If you’re looking for easy, I’d buy the quicksilver that’s tuned for the motor already. The carb I received idled too fast and even if the throttle wasn’t stuck open it wouldn’t have run well with a racing choke (screams air leak because of poor quality)

Throttle pin defective

This carb fits my tohatsu 3.5 hp but the throttle pin is defective. The only way to regulate it running wide open is to choke it out.

Great replacement kit

Color: Black

Water pump kit fits perfectly on my 200hp mercury outboard 2000 model. Excellent quality matching the OEM part I replaced from wear & tear. There where however extra gaskets & O-rings that go nowhere on my outboard
