Top Speed BUT NO POWER IN LOW RPMS

[sirhiss]

Hey
I have a Seadoo Rx Carb ski and the last 2 month it ran fine.
But till Friday I got the Problem that It has lower power at the Start.
It takes nearly twice as long to get on Speed as the days before.
It's very hard to pull a Wakeboarder out of the Water and the days before it had no Problem With two once..

The Pump isn't Cavitating, and if It got higher RPMS it runs well at Top Speed.

I've allready flushed the Fueltank,cleaned the Fuelfilter and checked the Rave Valves (can be moved easiely).

Excuse my bad english

Check/ clean carbs and fuel selector. Also make sure hoses are on secure. You sure you don't have a rope sucked up in the pump or maybe some weeds?

So I've cleaned the fuelselektor too.
I'm gonne lift the Ski out of the water today and inspect the Jetpump.
I hope there is the Problem...
Carb. cleaning is such a nasty work ;(

ok. I took the Ski out.
inspected the Jetpump and it seems to be all ok with it:
-Everything clean
-Wear Ring in good condition
-Prop. fine

Could a bearing cause such a Problem?
becaus Top speed is no Problem.

And what is with the Relay which is controlling the Rave Valves?
