Bogged down for now reason :(

[xplayer2885]

yesterday im on my slt 750 goin at around 5400-5700 rpm at most. An all of the sudden the damm thing bogs down an shuts off. It restarted a couple seconds later. Then it wont idle. The rpms would drop from 1100 down to nothing. I raised the idle speed in the water. I then rode back to the marina, an its riding just fine. I take the ski outta the water an theres part of a plastic bag around my drive shaft. Could it be the bag was so big it stoped the prop? or is it that my carbs are in desprate need of a rebuild? I plan on doing them this winter. An also when i checked my plugs they looked fine. Help guys

It may have been that the bag may have blocked the intake making it heat up.Semi siezing.When you stopped it fell and was resucked and wrapped.

Remove the bag and try it again. You'll know right away if it's your carbs or the bag.

Will semi seizing total a cylinder??

[xlint89]

Not sure, but crank index may be affected by the impeller binding.

Xlint89, What is ment by the crank index.

Your pistons must be EXACTLY 120* apart on a triple cylinder. If they are off, your engine timing is off and will not run normally. Polaris uses a press fit crankshaft, meaning it's not welded in any way. So, a hydrolock (water in combustion chamber) or a stick in the jet pump can cause the crank trying to spin, to twist. Thus altering engine timing and performance in one easy foul up.

Thanks, so if i remove the plugs and bring the front cylinder to top dead center, mark my shaft then rotate the shaft 120* the middle cylinder should be at top dead center and again for the back cylinder.
If the timing is off how can i get it back in time.

You cannot get your crank index corrected without removing it from the engine and having a professional do it for you. Try putting your CEN piston at "true" TDC and measure down to the other 2 pistons. It should be identical, or REAL dam close. No more than 1mm difference I'd say.
