Hello ,

Bought a used 2008 seadoo challenger 180 215hp. Boat has 62 hours on it, took it for the first ride of the summer yesterday. It started fine but seemed to idle a little bit rough and then when accelerating it was very choppy and rpms were up and down when throttling up as well. This lasted about a minute and then the boat ran perfectly fine for the hour I ran it. I shut it down when we got to our location and sat there for a half hour. Started it back up to leave and repeated the same thing again for about a minute and then ran fine the whole way back. Should I tune the boat up? Filters , plugs etc? Could it be the gas that sat there since fall possibly ? I’m new to this boat any help is appreciated. Thanks in advance.
 
There really are no tuneups for these…other than changing the plugs,,,also,,,load test the battery.
