2003 Seadoo GTX Di

[Shan]

Got a buddy with a 03 seadoo with the 951 and from what I've seen they should run between 50-52 on gps but his is only getting 45. Was just curious as some of the first things to look at that would cause this much of a speed drop.

Also his speed isn't registering on his speedometer but I wouldn't think that would effect his speed would it?

spark plugs, then power valves, check for full throttle, bad fuel, fuel filters, fuel injectors, air injectors, could go on, get it plugged in to see some faults

+1 on this. Plugs, filters , raves first and maybe even check your wear ring . What kind of RPM's are you turning?

I'll have to check the tach and see what its pulling... When you lay into it on take off it starts to pull good then it sounds like it cavitates and catches the limiter and hooks back up about 3 times and then it pulls all the way to 45.

I'll check the raves out for sure... How often do the pumps on these go through bearings?
