I have a S2 7.3 with a functioning saildrive. I had some problems with "old gas" recently which resulted in an adventure that was resolved since we could sail slowly out of harms way. While crossing a shipping channel, a container ship 1/2 hour away gets pretty close when the wind dies down and the engine dies shortly shortly there after. I am considering a small outboard as an emergency backup, and need some advice on engine type and mount. It wouldn't get much use (hopefully). I'd prefer fuel injection but haven't seen that in small outboard engines. Does an electric outboard even merit looking at?Thanks,AIS
