There's no way they used fiber gears in the drive train, those gears need to be as small and rugged as possible to handle the power without adding drag and steel is the only way to go. Yamaha used a badly designed fiber gear in the first generation 4 stroke to drive a counter-balance shaft in their engines, but I hear that problem was addressed at least 15 years ago. I would not hesitate to buy a Yamaha, they make a great product and there's a reason they are, by far, the biggest outboard engine maker in the world.
