SOURCE: 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

pull out the cat temp sensor and check to see if its bent. if so then its definently your catalist, even if not bent chances are still good it has failed. you need to be sure which light is coming on. does it look like a tube with squigly lines going up?

Something was stuck to the intake obstructing flow.
When you shut it off it drifted away.
It is a good practive when in weedy or heavy debree areas to get clear shut the motor off count to 30 then restart and gradualy excelerate to make sure it is clear. used this method for ten years now and seems to work well for me.

It Runs but has very little power,quits often,if you give it to much throttle it bogs down


Robert, First try new plugs, check fuel filter, sounds like it could be carburetor/injector issue, dirt,plugged jet, etc. Remove and clean/rebuild carb./injector.
Check the attached links,instruction and guides, Good luck

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.

Waverunner is abnormally slow accelerating initially, but will finally get up to normal speed


Pull your air filter out and also replace plugs. Overtime the filter will become saturated with oil and believe it or not the plugs can cause about a 10 mph drop if there going bad. But make sure your pump and impeller are not damaged also

Yamaha wave runner check engine light comes one and will not run properly.


Have the fault codes read. Replace faulty items. Use only
genuine items as replacement as non-genuine are not always compatible with the OEM fitted CPU units. This results in the fault codes not cancelling out.

Got my 2009 Yamaha FX sho waverunner under water, drained the water from the hull and tried to start it. Turned over 5 or 6 times and stopped. Pulled the air filter out and of course had water in it....


remove all sparkplugs and hold full throttle and crank over several times to get water out of cylinders ! have a jump pack ready as battery will die ! use carb cleaner on the plugs each time you try to run after this , hope this has only just happened as internal damage might already started ! if all ok check the engine oil also as water normally gets in after this problem ! if oil is milky then change oil several times , run for 15min on hose each change until oil normal colour ! then you must take for a run for an hour to help dry it out !
