I am losing faith and need help :(
I have decided that before I completely get demoralized, that I should ask everybody for direction. This is the second polaris I have bought in a month, the sl900 is a disaster but I'd rather get this one going because it has more potential and it looks brand new. I bought a 99' slx and it stalled on me when I hit a wave, after that I tried starting and somethign was preventing it from turning over. I really did think this one was goign to be Mr. reliability. I have it turning over again but here are the facts as far as I know:
- this thing has a history of jet pump trouble, it eats bearings
- Compression is perfect
- Charged battery
- cannot turn crankshaft by hand
- I have yet to see a spark
- impeller looks great
- plugs are new and they are the correct ones
- carbs are newly rebuilt
- splines on drive shaft are perfect
Where should I start? I have the feeling this thread could be a long one, and its very important because I am seriously debating having to exit the sport
It really bothers me that the thing jammed while trying to start..I had to get towed back to shore and it wasnt fun.

First pull the pump and plugs and then see if you can rotate the engine by hand.

Oh as far as eating pump, shafts etc. Check the pump to engine alignment and make sure it's good or you'll just do it again.

Like I mentioned in your other post, (and Ph2ocraft said above) give that pump a good looking over. I would almost bet that your problem will be found there.
Can anybody confirm that the pump from his sl900 will fit this slx?

If you can't figure it out let me know. The guys at Black's Corners in Carleton Place have some good experience with the Polaris platform and I can probably get you in quickly.

guys... this is my old ski.. i sold it to Cal
The bearings were installed properly using the appropriate sized bearing and seal pusher kits.
you guys might remember i did a bearing kit on it also in like June or something? anyway... since then, it has a new impeller shaft in the pump bc the old one had the inner races and spacer between them seize together...
i'm thinking outloud.. what can cause the bearings to literally explode apart and the inner races and spacer get like welded together... something with the prop, or something with the length of the spacer causing something to bind when the prop is fully tightened which essentially pulls the bearings in together tighter if they aren't bottomed out already?
luckily i gave him a spare complete pump rebuild kit when he bought the ski so the repair shouldn't cost much if anything... just a matter of what the chronic cause is...

I would have to think water intrusion but that could be do to lots of things including engine alignment

correct me if i'm wrong... water intrusion would lock up the pump only after it cooled and rusted, no? .... so long as the ski is always running and spinning water is only going to cool it.
