Question

I have a 1999 Yamaha WaveRunner XL 1200 X.

Two days ago it started to have trouble starting. It didn''t want to idle it would just start and stall. If you are quick on the gas you could get it going and once past slow speed it was fine.

I took it for long run yesterday and first started to notice that it seemed sluggish at anything under half throttle as if it was running on two of three cylinders. Once past half throttle it would take off and perform normally. As the cruise went on it seemed to be getting gradually worse. After 45 minutes of cruising slow and fast, I went to slow down and it stalled with a clunk at about 1200 rpm before reaching idle. There were never any warning signals to indicate anything was wrong.

From that point on it will not turn over. You push the starter and you just hear a click as if the starter motor is straining to start but the battery is weak. We tried to jumpstart it but still the same thing. Some of the battery cells were low on water, so we filled them. We charged the battery overnight but still just click when the starter motor engages.

I thought something might''ve gotten twisted around the impeller or driveshaft, but it seems clean. I pulled the plugs and they seem normal, all of them look the same.

What do you suggest?

Thanks Michael
