    Seadoo 2004 GTX SC Pump Housing

    I recently purchased a 2004 GTX SC. I am in the process of rebuilding the jet pump assembly. I am upgrading the impeller and replacing the wear ring. I noticed the venturi had a crack in it and that is also being replaced.

    However, upon inspection of the jet pump housing(10 Vane, 155MM) it had a small crack in two of the vanes and a decent amount of ware on the bottoms of the fins due to debris hitting. My question is is this still usable? And if not what are my possible replacement options? Ive been searching for used pump housings online and can not seem to find any. Is it possible to use a pump housing from a different ski model also?
    Thank You

    Sounds like this is a plastic pump housing. If so replace it with an aluminum housing. I believe a 2005 GTX aluminum pump should fit just fine.

    Thank you for the quick reply. I did some research and came up with this. https://www.parkeryamaha.com/seadoo-...267000417.aspx for 200$

    Will this pump housing be compatible with the 2004 gtx sc? I'm just trying to get more experienced advice, because I am not an expert. Thank You again.

    Yes that will work. You obviously need the internal bearing kit parts 8-11, a new wear ring, and impeller.
