Is there such a thing, and where would I order one? I've heard they are cheap "emergency" props to get you back to shore. My boat is a 4.3L Mercuiser (1995), so fairly common. To get the exact prop info, I'll have to dig a bit deeper.
The prop in the above link is not a temporary prop though. They were designed to be repairable by replacing the blades when one is damaged. They are a little cheaper in some cases than an aluminum but not by much, then when you purchase a set of replacement blades you have invested a small fortune.... i never heard to many good things about them they tend to flex big time and rob performance and damage easy. I would not spend $130 + for a spare prop I might never use....Plastic vs a rock HMMMM
I carry my old buggered up prop as a "emergency prop". Look on ebay or go to a marina you should be able to find a junk one really really cheap. FIY I would also get spare washers and a extra nut, They dont float too good when you drop them doing a emergency swap-out in the water.

Woody, in my opinion you would be better of with an aluminum prop as a spare. The plastic props aren't any cheaper and they certainly BREAK a lot easier.
