    1997 Seadoo hx Factory pipe Question (ECWI)

    I purchased an hx with some aftermarket stuff on it. Im in the process of going through it and fixing misc issues. One thing im not familiar with is the factory pipe. Ive read alot about it and the issues that come with it. The one i have does not have an ECWI installed. Is there any good reason for this? Thanks

    It could be hard jetted I guess. But I think it would be almost impossible to ride like that.

    Can you explain what hard jetted means? Also i should have been more clear. There is no water line going to where i think the ecwi jet goes. ,on top of the ex manafold.
    There is just a plug......

    The ECWI controls the amount of water being injected into the pipe at various RPM's. The Factory pipe is a very stout setup and it needs the water injection to help give the pipe some bottom end. Some people will use carb jets of a particular size to obtain just the right amount of water flow for a certain RPM. The problem with that is you will no longer have power everywhere. It will only have good power at a certain RPM and be very unrideable as far as recreational is concerned.

    Thanks thats what i thought. I decided to build the ski for the sport spec class. So i will be removing the aftermarket stuff and going back to stock.
