A couple weeks ago I picked up a 1997 XP that I was told was in running condition, but it may have been a year or so since it last ran. Since getting the ski, I have not been able to get it running. It seems like the starter is turning extremely slow (or not at all?) when the spark plugs are in the cylinder head. However, when the plugs are removed, the starter turns over quickly.
I have been looking at other threads on the forum trying to determine what my problem might be and different ways to troubleshoot but I have not quite been able to solve my problem.
I bought a brand new battery when I got the ski, so I doubt this is the problem. I also supplemented the battery by hooking it up to my vehicle battery (not running) with jumper cables and got the same results. I next took apart, cleaned up, and rebuilt the starter motor with new brushes and seals. I additionally cleaned up the electrical contacts for the starter cables at the starter end and the battery end. I also checked the starter solenoid by jumping it with an insulated screw driver. The resistance in the ground wire and positive wires to and from the solenoid were all very low (0.02 Ohm). When turning the starter over with the plugs out, the voltage between the negative terminal on the battery and the positive on the starter is 10.5V. The compression on each cylinder is 145psi.
I also thought the ski could possibly be hydrolocked but after turned it over countless times (for a short period of time, giving starter a break between attempts), no oil or water has come out of the cylinders. Checking from the rear of the ski, the jet does turn and I can feel exhaust pulses when the starter is turned over without the plugs.
I have included two videos: one showing the ski turning over with plugs in, and the other without plugs.
Any thoughts or suggestions on what to try next would be much appreciated! Thanks in advance!
