Do a search, this was beat up recently by a member and someone affiliated with Parsun/Sail or whatever they are called this week. Some parts are Yamaha compatible, but not all, but then why would you try to save money at purchase, then buy over priced Yamaha parts later on? I personally don't own one, and probably never will, my only first hand info on them is a 9.9? my mate got some time ago, from new it was almost impossible to start, various warranty "repairs" left it still useless, to this day, it's under a bench in his garage, he ended up buying a near new second hand "brand name"
