  • Yamaha sells shaft drive oil. I'd use that

  • I used 90wt gear oil in my 250es

  • if it has water in it, or real nasty, yes flush it.. won't hurt..

  • 80 90 gear oil

  • Try to change it before you ride it anymore. This is what mine looked like when I bought it.

  • O jeez I do a lot of mud and river riding . Mine probably looks the same

  • I'm just not close to a Yamaha dealership

  • River rides will get you. I change oil every time I get done with the water

  • Not sure bout yammies but use hyoid gear oil in the Hondas. Probably same

  • If you run mud and river run your breather line up higher helps out a lot. I have one built for the mud change it three times a year with Yamaha diff lube. Or any other diff lube I have laying around.

  • Yeah I've extended all line the to in behind the headlight
