This motor runs off of propane instead of gasoline, either from a lightweight canister than I have for sell, or you can connect to your propane grill tank with the included remote hose. The motors weighs only 87 lbs., so it is great for portability to and from small boats. It can also be stored all winter without concern of the carburetor gumming up like conventional gasoline tends to do.
Rather than taking the motor out of the styrofoam crate and placing it on a stand, I added some images of a 15 that looks very similar.

These motors cost $2,400 new.
I also have other motors, boats and trailers. Here are most of my ads: http://charlotte.craigslist.org/search/sss?userid=13325410
