    2012 GTX S 155 - what should I know/ my rebuild & repair

    Hey guys,

    If you haven't seen my thread "OEM rebuilt long block", I picked up a 2012 GTX S 155. It needs some (a lot) of TLC. Its gonna need a full engine rebuild, and cleaning/replacing some of the wiring harnesses (it sunk part way in salt water). This is my first 4 stroke ski, and my first Seadoo (have always had 2 stroke Yamahas.)

    So anyways, is there anything I should know before I start to dig into it?
    So far I've got the top deck off and sucked out a bunch of water from the crank cases. lol not good!
    Also power washed all the salt water/ ocean grime off.

    This will also be my rebuild thread so I will update with more pics as I get stuff done!

    Thanks, and heres some pics!

    Before cleaning

    After cleaning! Cleaned up pretty good.

    you don't need that much only.
    motor $2000
    harness $500 if a sunk on salt water
    maybe ecu $500..and you ready to go

    I dont know if thats sarcasm... kinda hard to tell. But if it is, yea its gonna need a lot. But I got a REALLY good deal on it so I have a lot of room to buy parts and still make a profit. I mainly started this thread to see if there were any things I should know about these jet skis etc...
