trouble hitting top speed

[Varycoolman579]

Hi i have a 2006 seadoo rxt 215 and my doo is having trouble hitting its top speed, i go full throttle and past 40 mph my seadoo starts kicking as if the spark plugs are skipping a shot. i figured it was the plugs and took the entire spark plug assembly apart cleaned them and re greased then and re installed them. but still the same problem. does anyone have any idea what it could be and what i could do? also if anyone has any diy modifications i could do that would be great. Thanks

How does your supercharger look? When was it last rebuilt? At what rpms does it start acting up?

 

[Varycoolman579]

i dont remember exactly what rpms but my supercharger was rebuilt last year around 40 hours and it currently has 72. i think the rpms hit roughly 4500 fine and after 5000 it starts skipping

sounds like its hitting drown mode or maybe you got the learning key on. Do you have any engine lights?

 

[Varycoolman579]

No lights or beeps and im using the main key. whats drown mode?

 

[pwgsx]

Sorry wrong word. It's like limp mode. Computer drops engine rpms when something is wrong.

is there any way to find out the problem?

 

[pwgsx]

You would be getting a engine code or light if it went to limp mode so I doubt that is it. Silly question but anything stuck in your pump..is it cavitating?

i'm certain there is nothing in the pump because i can do everything but reach top speed like donuts or jumps
