Question about Yamaha 12V Air Pump
The rooster tail on my 2007 waverunner is only shooting up about 2 foot. Could this be a problem? It used to shoot much higher
If the waverunner is performing normally as far as throttle response and top speed, then the rooster tail not shooting as high as it used to indicates there is a restriction in the nozzle for the rooster tail, not a problem with the ski. Unbolt the rooster tail nozzle from the steering nozzle and inspect it for debris.

Testimonial: "Thanks for the info. I will give this a try."
There is a hose running from the jet pump housing to the nozzle. You might try taking the hose off of both ends and verifying that the hose/nozzle is not blocked. If it is, blow it out... if not it could be a partial blockage in your jet pump... are you noticing any reduced power/speed/cavitation on accelleration?
