    seadoo 185 sc smoke help needed

    hi guys im new to the site and need some help!

    right i have a 185 sc with 84 hours when i bought it last year it was minus 7 and when i started it it smoked on tickover... when i got it back i took it to a jet ski machanic who said it was way to smokey for a 4tec so the testing began!! the compression was in the 130s and oil was ok so i took it out when i was out it went ok no problems at all apart from smoke. after about 2 hours we bought it in and it had used no oil water etc just down on power? due to worn impeller now done. right so to cut the story short i have had new complete set of rings and valves gaskets etc i have changed the oil seal in the s charger and still it smokes on tickover it smokes minamal but when i give it some power it smokes alot???? it only seems to be when i put power down??? it has a modified exhaust and water box and when i looked on you tube there were some on there which smoked like mine? has anyone have any ideas?? thanks guys

    Your gonna have to start from scratch. Check your plugs. If its coming from a combustion chamber one or more of your plugs will show it. Then do a leak down test...

    The supercharged 185 has the intercooler in the intake manifold. The water for the intercooler is provided by the jet pump, not the closed loop cooling system. You could have a very small leak there. That water would be vaporized in the combustion chamber and cause white smoke. Since it is nine years old I would remove the intercooler and pressure test it. If it was bad I would replace it with an external one. The ski theoritically may run a little better. Like it has water injection.

    Nope. No IC in that ski. I hope you pay more attention to the sikorsky manual...

    i dont no then i have changed all the bits ie sc oil seal gaskets rings etc just spent over 1000pounds on it now!!! i cant see why its doing it? does having a modded water box and exhaust cause it as i have seen on youtube that others smoke like mine with thease mods?? also i have only done 4.5 hrs run in time??
