Prepped the 2007 Seadoo Challenger 180 last weekend (21 May 2011). Changed the Oil, Filter and Spark Plugs...have done this before with know problems.
I did have about half tank of leftover gas from last season, but put Marine Gas Treatment in tank before buttoning up for the season.
Took the 2007 Seadoo Challenger 180 out today (30 May 2011) for the first time this season. Boat started-up and took off with no problems. As soon as I opened up the throttle though, I immediately noticed the boat revving / stuttering, and RPM's would only hit around 6000. It appeared that some white smoke came out of the back end, but wasn't significant. No smoke in engine compartment, and no signs of leaks.
Any ideas what's wrong?
