    What carb to I have?

    This is my first experience with a seadoo, so all the help I can get would be great.
    I have a 95 GTX with a 657x engine, and it looks like I need a fuel diaphragm. I have no idea exactly which carb I have, but from the Manual it says BN 38, but from reading on the forums I'm not sure exactly what I have.
    And, do I need to buy a whole carb kit or just the fuel pump kit?
    And, where can I order this?

    I think the twin carb 657s and 717s both used a pair of 38s. I have only seen those parts in a kit, but perhaps someone has a source.

    The good news is that I think there are only two kits. One for the 46s and one for all the others.

    You could get a diaphragm by itself from PPG who gets them through Hot Products who gets them from Mikuni the OEM for your 38mm Carb.
