The only one I could find after doing a search needed a hub conversion kit. Me personally, I'd stick with aluminum as it will give if you were to hit a solid where stainless will immediately snap the shear pin and puts that momentary torque on your shaft. If you're bent on doing it the site I found it at is; www.danspropshop.com. The prop is $220 and you'd have to ask them about the conversion kit, no doubt expensive.
