Just purchased a used Sea Doo Challenger on E-Bay in Mesa Arizona and transported it back to COlorado. I can only get the boat to 34 mph and 6700 rpm, yet I have heard that they are supposed to go faster. It now has 12 hours on it and it has the 215 HP engine. I am currently running 85 octane. Any suggestions?

What year is it? Did you verify the supercharger washers are all there intact?

Sorry, year is a 2008 model purchased with 5 hours on it. Unfortunately the closest SEA-DOO dealership for me is 80 miles away.

pull the hose off that goes into the supercharger and see if u can spin the supercharger wheel by hand, if so the supercharger washers are toast and u will need to pull the motor and clean the screens in the front and rear of the motor and make sure all the washer pieces are out of it.

85 octane! Get that crap out of there and run 91-93 octane! Mine ran in the mid 50's on the speedo.

Thx JohnnyD. Is this a common problem with the supercharged engine?

Thanks H--do-O . Will do. My daughters boyfriend who is an aspiring engine mechanic told me that is the first thing he would do. Also my son said that the supercharger does not sound like it is working. (He has one on his car and it is very noticeable when it kicks in.
