speed

Hi there, So in 2003 i purchased a 2003 seadoo speedster. Over the years of storage from being away the boat has just sat until 2010. I was trying to look for an owners manual somewhere so I could do the check ups and make sure everything is running fine. I have put it on the water 6 times this...

Hey i was just wondering what other people with a 2000 SeaDoo GTX Milenium Edition with a stock engine got for their top speed. My speedometer showed 68 on a speed run but later i did a GPS recording and it showed 51 as the top speed and i couldn't believe that the speedometer was so far off.

Im just wondering what cheap modifications I can make to my seadoo to make it go faster. I cant afford superchargers and the pro stuff. Ive heard that performance intake grates can help. I run 93 octane strictly through it because its a two stroke and I heard that they run better on higher...

Hi everyone, I'm new here but have owned jetskis for a few years. I just bought a 2004 Seadoo sportster boat and took it for a spin... brrrrr (40 degrees in NY today, haha)... just to see how it runs. It only got up to about 35 mph and I'm wondering what I can do to make it faster. The...

i was wondering if i could add some mods on my 1997 gtx 787 to make the acceleration and top speed better? just got a new engine in it 0 hours still have to break it in. Thanks!

Hi, I have a new 230 Challenger 2008. The big problem is that no service engineer has ever looked at it and the two engines are not in sync. When the left engine is at 3,000 rpm the right is working at 4,000 - 4,500 rpm. This must obviously be wrong and my guess there is a very easy solution...

OK, I hope someone can help me out here, This problem occurs only at top end. Everything runs ok at idle and midrange. Will only run aprox. 25 mph as opposed to 40 that it use to run. I've dis-assembled the carb, cleaned it, and put it back on. That did nothing. I then took a carb off my...

Our 2006 GTI SE with 100 hours is experiencing higher than normal RPM (+500 RPM) and lower than normal speed (- 10 MPH and decreasing). One mechanic wants to replace the pump based on this description. Any other thoughts on possible causes?

My buddy says his 97 Seadoo GTI used to run 45 or so MPH, but this year will only do 37 indicated....is it an indicator problem or what should I look for to get him back to SPEED ???:rant:

:confused: I have a 1999 xpl I would like to know wat it is worth. It is bored out to 1051 ,pro-x pistons, miller head, water injection,2deg wedge, solas impeller, R&D ride plate and intake grate, jetted carbs, after market air cleaners,sponsons , i removed the sound baffle. This jet ski leaves...

I just rebuilt my carbs on my 96 challenger with a 787. Like many others, the plastic caps were gone. I have seen that the spec'd initial setting should be zero. Does this apply with the caps removed? I would like to get it in the ballpark before I take it out for a test run. Any...
