Paddled mine home a couple of weeks ago. Had run the engine for an hour in the barrel the night before, took it out at about 3/4 throttle for half an hour, headed back to safe waters, knocked it down to idle and the engine died. Wouldn't fire again no matter how hard I tried. Had to paddle it back about 1/2km with the wind behind me but pushing me out to open waters. Fortunately I'd planned the trial with the wind/tide so if things went wrong there was a plan B.
Have to say it wasn't too bad to paddle from the console, I'd recommend a good, stiff T handle type, and a pairs only any use if you've got someone on the other one.
