feul problem?

[Blazer210]

I am having an issue with my yamaha 225 vmax, it is a 2000 model and if just punch it to get on plane it will cut off, if i feather the throttle it will not do it,nor does it do it when i submerge the motor in the tub. any suggestios?
I just had to my mechanic and he replaced he o2 sensor and all the fuel filters on it.

Sounds like he did not clean the v s t filter

Is that very hard to do? also could you explain to me where it is located?
Thank you for the quick reply

Go to:SIMYamaha-Andy's Tips for step-by-step instructions with photos for VST service, plus several other repair/maintenance procedures....should be helpful! Good Luck!

Wouldn't tackle this without a shop manual and time spent researching the procedure. Lots on here and I believe some pics on THT.

you can try just draining the tank into a glass jar, etc to see if you have any gunk
the tank is located on post side of motor, the large alum canister, youll see a drain screw on bottom front

if youve ever taken apart a carb its not TOO much different
otherwards a manual/ online video will help much
