Hello, everybody! Recently purchased 2006 Sea-Doo GTX Supercharged 185HP Jet Ski. It has only 36 hours on it. There were some parts missing, like the jet pump housing. I purchased everything and put it back together. The jet ski runs just fine but the top speed I was able to get was 50mph at 6800rpm. 1 person, 2 persons it didn't matter-50mph. I took it to the dealer to check what might be wrong. They tested the supercharger and inspected the pump. Was told that everything is fine. The oil level was 1 quart low (i changed it the day before) and lots of codes showing on their computer (which is probably normal because all the harnesses were disconnected when i bought it). They cleared them and when tested on the stand there were no more faulty codes. Next day I tested it on the lake and it got to 55-56mph at 7100-7200rpm. From what I found on the web it should go 60-65mph. at around 7500rpm. I should say that I put brand new jet pump housing but the impeller is old and not in perfect condition. Any help will be much appreciated. Thank you!
