What was the top speed when you test rode it before buying?Just got this gti and it's lame. 77hrs, using yellow key 43 mph. WHY?
I believe you are using a "Learner" key. All my Seadoos (five) ranging from 2012 GTI 155 SE to 2019 RXT-X 300 all have green learner keys. The normal keys are yellow. Normal keys allow for three riding modes. Economy, Touring, and Sport. Check your keys and then your dashboard once running. The dashboard will show you which mode you are operating in. Hope this helps.So far I've changed the plugs and checked up in the intake grate area. The impeller and wear ring look good. The oil looked to be on the high side. I extracted about a half quart out.
The weather has sucked here (St Louis area cold and or raining) so I can't test ride.
It will tell you if it's a learner or normal key as soon as you put the key on.Perhaps your yellow key is programmed incorrectly. Go to a dealer to have it checked.
OK, so I just got into the Jet Pump. The impeller looks good but the wear ring has some wear that is more than likely causing the low MPH. There was also some water intrusion inside when I removed the cone.
I have grease, the wear ring, a WR011 tool and a new 267000206 seal. Hopefully this will get it going to 55.
