I have a 1990 Yamaha Waverunner 500...I bought it used...and it is in good condition for its year...?
The only thing is, when I start it, it wants to immediately go about 4 or 5 mph...I am guessing that the idle needs adjusting...Does that sound like it to you?...If so, then where exactly is the idle screw located?...If it could be something else, any feedback on that would be appreciated...

I would say that you are right in your assumption that it is the idle speed. To find the idle screw work the throttle and watch the carb. you should see a screw that touches the throttle lever back it out about 1/4 turn at a time.
