Some of the engines do use Stainless. I do not think the CX is one of them. However it has been my experiece as well that the Enya bearings do hold up much better to fuel and corrosion over time. Their metallurgy is very different and that leads to he longer life. We just lowered many prices on engines to help revitalize the line and to get more dealers to carry them. Hopefully it will work. They are great engines and hopefully we will be able to get Enya to release some newer enigines in the near future.

Yes the 50CX is chrome. I know the bearings they use are at least different sizes than other comparable engines.
