i was about to start a 2nd rotax conversion but changed my mind. these carbs have been cleaned and inspected and look good. the only thing that may need changed would be the PTO side diaphram. that is the easy one to change. it is 4 screws and 5 minutes.

the ski throttle cable and the choke cable is included. You can use the choke cable in the conversion.

this is the same carb set up that I used on my 670 and I can give the buyer (or anyone else) the specs on the throttle cable that you will need to order.

these will work on the 583 or 670. they are the same jetting from the factory for both engines. check here for info on the seadoo carbs

these are from a 94 spx 657

$165 shipped

would those work on a 44o Engine or would they be too much.

i am not sure on that.

one thing to look for is where the throttle cable connects. you want it on the left side for easy of the conversion. most are on the right side.

I ended up buying 3 sets of carbs before i figured that out
