2005 Yamaha FX won't go over 4 mph

I have a 2005 FX, it has been in the water a couple of weeks - kept on a jet ski dry dock. It was running well all weekend then when I pushed it into the water it idled fine and pushed water through the back but when I tried to accelrate the RPM's would increase but there was no power and it vibrated substantially. I could barely get enough power to get it back on the dry dock. Any thoughts?

    do i need to take it out of the water to check this? any specifics would be appreciated about what I am looking for, oh one other thing if I rev it out of the water it did not shake like it did in the water. I imaginge that has to do with the impelar pushing water and its ability to do so.

    thanks

If I understand you then this problem may be the jet impeller, check to see if it is loose or the coupler is damaged, is anything clogging the water intake to the jet.

What now ?? my yamaha suv1200 Can the transmission be shot ?


there are no gears just a direct drive from the crank to a jet pump ! if theres no propultion of water it could be several things !
1. plastic bag etc in the intake to impellor pump assy !
2. impellor gap to housing too much ie worn impellor !
3. impellor not turning because splines on either the shaft or impellor worn !
4. drive coupler damaged and spinning on shaft !
Try running on a hose pipe and look at rear of engine ( remove plastic cover so you can see the 2part coupler and drive shaft ) .
Check the impellor assy !

Why does yamaha waverunner fx cruiser ho not run in lake but will run hooked to water hose


Sounds like you have a bad stator. It may be producing enough spark to start the motor, but under a load (as in the water) it simply can not supply the amount of spark needed. Sometimes when a stator is tested on a ohms meter it may test good, but still be defective do to the load it will come in contact with when put in the water.

2004 waverunner fx cruiser, ran great last time out. Now hard to start and wont run on high speed. Nothing over 6 mph.


How old is the fuel? Ethanol causes major problems if left too long. You may need to empty the fuel and clean out the fuel system. Try changing the fuel filter and adding some seafoam to the fuel and running seafoam thru the fuel system. Hopoe this helps.

sounds like you hydro locked it and possibly blew out a reed in your engine intake or worse, you may have bent a crank rod. But before you go tearing it apart make sure all the water is out of motor and theres none in the fuel tank then put in a new set of plugs and see what happens,
