I just bought two used 06' GTX waverunners.. One is supercharged the other is normally aspirated.. They appear to be in good shape but I did notice a missing o-ring on one of the hull drain plugs.. I called 4 dealers looking to buy the correct replacement o-ring only to find that I would have to buy the entire drain plug assmbly for 12 bucks each. No dealership was willing or able to sell me just the o-rings.. My waverunners are two hours away and I was too stupid to bring an o-ring home with me so I could match it up at a hardware store.. Does anyone know the exact size o-ring I need for the drain plugs?.. I bought an assortment of o-rings at home depot thinking I might get lucky but of course HD doesn't sell anything metric... The oil and filters have been changed in each machine, I ordered two new batteries (AGM) as the originals are still in there and only reading 12.1 volts resting. The supercharged one seems to crank slowly. I sprayed some corrosion X inside around all electrical connections and did a general inspection/clean up of both. Any maintenance "gotchas" I should be aware of with these things?.. I've never owned one before but these waverunners are so much fun to ride I can't believe it...Thanks
