Sounds like the impeller is knackered, check the impeller housing and the impeller itself, impeller should look like its nearly touching the housing, check the housing to see if it has created a grove, if they both look worn, replace with new

99 yamaha waverunner 1200 xlt starter stays engaged and powered on even after stop is pressed and kill switch is pulled.


The start stays engaged the entire time? I would guess it's a bad ignition switch -- it would be sending power to the starter (through the solenoid) regardless of if you switched it off.

Maybe it could be a bad starter, too. I'd start with the switch.

Yamaha xl1200 waverunner losses power after it is warmed up.


Hi, most likely cause and the easiest to check is exhaust leaking in the engine compartment. Run it without the seat fitted for the same time frame and if it fixes your problem you are looking for an exhaust leak. Regards Phil.

YAMAHA WAVERUNNER 2000 XL 800, WILL NOT RUN PAST 12 MPH


Have you done a compression test on all cylinders? My guess is you have a dead cylinder (no oil to one or more cylinders causing loss of power). If the compression test passes (all cylinders equal and higher than 100-110 psi) you have a restricted exhaust from a failed catalytic converter that has broken apart.

2006 yamaha waverunner wont idle


what is it idle at? how much? remove your seat check air filter if is black oily remove it and see if that fixes your problem you may want to change your spark plugs as well # one cylinder may be starting to foul the new yamahas are the worst for fouling plugs use a cr8eb instead of the cr9eb the 8s are hotter and work better try those and let me know thank you
