Purchased this beautiful 1998 gtx rfi back in April. Seller started it right up for me. Me only owning 1 xp prior didn't really know what I was supposed to be looking for. I got it home and started fixing the small oil leak coming for the oil pump. Then I realized things just don't look right in the engine bay. Did some research and found out the seller took all the components out that made it an RFI, and converted it to twin carbs. The 2 most important questions I asked him before handing over 2k were "is it a true rfi?" and "is it water ready?". He replied yes to both questions.
I dropped it in the water when I got home, and it took on a ton of water. Pulled it out and fixed all that. Basically put an entire exhaust on. The reason for that was because he took parts from a few different seadoo's to make this conversion work. The exhaust now was ran on the opposite side of the motor. The same side as the hull exhaust outlet! Anyways, I got that all buttoned up. Replaced all the fuel lines, did a full rebuild the the carbs, cleaned the rave valves, new plugs, etc etc. I ran through basically everything except rebuilding the 787 motor.
I finally got it to stop fouling the plugs and it ran so good for 10 minutes in the water. Then suddenly I felt a big loss in rpm followed by an awful noise from the cylinders. I wrecked the motor. GREAT!
Prior to my test run, I tested the oil pump, replaced and primed the oil lines. I even checked while the carbs were off that the oil was making it to the valve intake cover fittings. Set the carbs to factory 1997 seadoo GTX settings, used the seadoo recommended 2 stroke oil, put the correct spark plug gap and much more.
This was an all summer project. All the research and work I did made me happy for 10 minutes on the water lol.
I'm finding it hard to walk away at this point. Should I find another 787 and swap it out, or do you guys think this Frankenstein of a jetski has seen it's final days?
I'd hate to dump more money into it if this setup just isn't meant to be.
Thanks!
