Other then racers we cruisers tend to avoid capsizing by reefing early and a few other precautions.
Having said that it does happen, like the other day when I was caught by a wind whirling around the pillar of a huge motorway bridge. Luckily it was with my old boat and my old outboard, a gas guzzling 1998 Suzuki two stroke. All it took to get it running again was to remove the spark plug, give it a few pulls on the starter cord, until all water left the cylinder. Then I put the spark plug back in, and it started on the third pull. I never worried about the outboard getting submerged at all, as long as you rinse it well with sweet water afterwards. A two stroke is lubricated by the petrol so no worries there.
I worry much more about my current Honda four stroke. When it is turned over the wrong way oil from the carter flows in to the cylinder. I am not sure if that is just as easy to fix as the water logged cylinder of my old Suzuki two stroke. Also the Suzuki did not have any electronics, all it had was a coil that was waterproof because it was embedded in resin. I have no idea how the modern electronics in our eco-friendly, low fuel use, engines behaves after it has been submerged in sea water.
Over the last two years, I left the engine in the car most of the time. I just felt no need to use it. On the odd occasion the wind dies totally there is always some yacht willing to give a tow. It is better then dragging the big, never used, balance disturbing. “anchor” along on my endeavours. The reality is I never need the engine and I rarely use it.
