Thru hull open or closed underway?
Here’s a poll to ask if you religiously close the thru hull while underway or leave it open. I religiously close it...problem is that I didn’t religiously open it (while battling high winds) and I think I will leave it open while underway just to have one less thing to do under scary circumstances.

Not sure why you would close the engine intake thru hull while underway?
There is a very high probability of needing to start your engine. I can think of other reasons for closing it... but not while out sailing.

. . . and such practice dictates working anti siphon protection in the exhaust injection line for safety - either a valve or a vented loop (my preference).

The concern for me was flooding the engine

I found a checklist on my boat when I bought it that directed closing the raw water valve once shutting down the engine underway. The procedure to start was the same for starting at the pier and underway, and included opening the valve after the engine was running.
My practice is to leave the valve shut while starting next to the pier and then leave it open underway. I also get nervous about flooding the engine, and more often than not I will get antsy while cranking underway so I shut the valve then go back to starting. I’m sure takes less than three seconds to start, but it feels like minutes to me. |

Bottom line - closing the thru-hull is a band-aid covering up an issue that should be fixed.

When I start the engine after its been sitting a day or more, I make sure the water intake is closed before cranking, in case the engine proves difficult to start (a frequent occurance in colder weather). I open the valve as soon as the A4 starts.
When the engine is warm, or has just been run within the last few houre, it always starts right up, so I leave the valve open while sailing. And yes, I do have an anti-siphon loop.
