I was hoping you guys could give me some tips and advise as far as troubleshooting some issues with my ski. I'm a "car guy" and always work on my own stuff, just pretty new to skis.

I've got a 2004 GTX 185 with 177 hours. When I bought it @150hrs I was told it had upgraded valves, rebuilt blower, and was otherwise stock. A few weeks ago I took it on a ~50 mile ride, the ski ran great, no issues at all. When I got back to the boat ramp and pulled the plugs a large amount of water ran out. It wasn't enough that it affected performance enough to notice (although I was just cruising around), but it was certainly out of the ordinary.

I suspected an exhaust leak, and pulled the whole exhaust out without finding anything obvious. I took the ski out again to test, and try to find the leak. I couldn't find the leak, but this time noticed it was ~10mph slower than normal and could feel some slight hesitation at times.

Researched some more, suspected a failed carbon ring, replaced it, and went back out for a test. This time the ski is bone dry, no water leak at all, but the hesitation and slower speeds are still there. I rode around for probably 10 minutes before the ski just sputtered and died. If I hit the starter it would turn over, but sounded slow to turn and wouldn't start. Eventually it stopped turning over, which I assumed was the battery getting weak.

I got the ski back home, charged the battery and still it won't turn over at all. I pulled the plugs and they look fine. Looked in the cylinders as good as I can and don't see anything obviously fubar'd. I pulled the intake and the blower moves a little (like 1/16th of an inch) so I don't think it's seized. Oil looks clean and is full. I'm just a little stumped at this point. I assume pulling the intake manifold is next on the list, but I feel like if it dropped a valve I'd see some evidence in the plugs/cylinders. Any other things to check or stuff to try before I get ready to pull the motor?

Thanks in advance for any advise. Really hoping this thing isn't totally dead.
 
had the same symptom on my rxt 260- turned out to be bad battery connection at the solenoid, even though it felt tight. I replaced the battery and cleaned the solenoid terminals and that resolved the issue of slow cranking and no starting. (until the timing chain went and destroyed the engine) - regarding the water in the hull issue- mine would always have a small amount- it never raised an alarm with me.
 
Awww man, that would be awesome. Now that I think about it, the new symptoms (not specifically water related) started after I installed a bilge pump. That'd be amazing if the battery connection was causing all this. Can't wait to get home and mess with it now.

And I should have added that I had to put a new battery in it because even with the old battery charged it was still too dead to crank the engine over and power all the electronics. I was suspicious of a bad connection after putting in the new battery and still got the slow crank, once I check the connections and cleaned them, it's spun right up. And you mentioned that you have water in your hull, so if your bilge auto switch was activated while you're riding it the whole time that would easily kill one of those small batteries. I would put a new battery in it and disconnect the bilge sump and see what happens.
