2006 seadoo supercharger

[Franco3687]

Just a slight problem occurring my jet ski is toping out at 45mph sometimes reaching 46 mph but not going any further then that I checked the super charger blade see if I can spin it and I can not I checked the tube connected to see if any suction was happening when given acceleration at 4000rpm and the force induction is working ...what else could it be maybe problem with key?

change your plugs

 

[Coastiejoe]

As noted, change the plugs as 4-tecs LOVE their plugs. Cheap and nothing to lose.

That said, everything comes back to a SC issue based on your max speed.
All of you complaints lead me to believe that you have a SC and or SC related item issue. A hole in the hose, a hose collapsing, a loose clamp and or the SC itself.

You say there is no play in the SC. But did you physically check what the slip is with a torque wrench?

 

[Franco3687]

All hoses were checked, Supercharger is fine, air was being forced out, sc hose was flexing at 4,000 rpms, and spark plugs were changed.

need more info. what max rpm does it reach at max speed? does it start, idle, and run fine? does it accelerate fine with no cavitation(feel like it's slipping)? oil level midway between notches on dipstick? what year and model?

 

[Franco3687]

7800rpm at 45 mph which is max speed idle goes towards like 3 mph...it runs fine accelerate is good no cavitation oil level is fine as well and 2006 gtx seadoo 4tech
