    RXP vs RXP-X motors

    Is there a big change between the rxp and rxpx motors besides the sc? Just wondering if i can use a rxp motor in an X with the same power output. Any knowledge would be great. Thanks!

    The x engines also run bigger injectors 42's compared to a 215 motor 38's, and i think they also have a bigger fuel pump. Correct me if i am wrong. im not sure.

    Dont forget the external intercooler, but i think you might find your wrong about the fuel pumps.. Just different ECU's. But then again, it could be me that is wrong

    there are differences with the bolt on stuff mostly mentioned.but internaly they are the same

    fuel pump is the same the ecu runs it at a higher voltage ..that makes it deliver a bit more volume..

    X Fuel pump is different. I am running an X Ecu with 215 pump and is a bit lean.
    I was hoping that was not the case but, its different.

    You can't use an early motor out of a 2004-05 in an X, without switching all the electronics. Seadoo also has had some problems with the rings in the 2008 x-ski's, fixed in 2009's.

    I was advised that they are a little soft. You can use a few ounces of lucas upper cylinder lubricant to help them last longer.

    Dont stress it though.
