SOURCE: my 1992 yamaha waverunner iii 650 is taking on

I know this sounds obvious, but make sure the plugs are screwed in.
usually 2 of them at the back of the waverunner.
i know i forgot to put them in one day and by the time i parked the truck & trailer it took on so much water the motor was half submerged.
Hurried and pull the truck back and got it out and let her drain iout the plugs, then fired it up.

anyhow, if thats not it then your hull must be cracked and leaking in, take seat off at the ramp and see if you can see where its coming from, if you don't notice anything, then its coming in through
the ports at the top of the wave runner under the steering assembley housing, those tubes are made to direct the water to the bottom, if you have an auto matic bilge pump, make sure that is working or it won't pump out the water like it is supposed to.
hope that helps

I have a 1991 yamaha waverunner wr500 there is gas in the engine compartment why?

Most likely a fuel line that has failed as a result of modern fuels with high levels of methanol. Given the age of the unit I'd expect that fuel is either leaking from a cracked fuel line or directly from the carburetor because one of the rubber diaphragms has been destroyed by new fuel. PS. never leave fuel in the unit over the winter or for extended periods of time. Try to run it out or drain the tank.

Rooster tail is not shooting high

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.
