I recently got a non running one of these for free. These videos were a big help. Also you don't have to spend 90 dollars on a new air filter, I was able to rinse it out.
we just bought 2 , 2006 FX HO Yamaha Waverunners and am in similar boat. I need to do plugs, change oil/filter and they have new batteries. I def need to run some new fuel and cleaner thru them,. I'm anxious to try them out for the first time since its still 100* here in San Diego until next month (Oct) . Had to get a Boater Card to legally run them in CA as well. I'm watching all your videos to see what if anything can go wrong with these models. Thanks
