Rightly or wrongly I don't close my raw water inlet valve on a regular basis but I do check my exhaust for flow when I start up. I do go through a routine on preparing to start and after start up and have a checklist at the helm. Another monitor that is cheap and easy attaches to the exhaust hose and warns of high temperature long before the engine overheats.

The Coot has a similar alarm/light panel:

Yep, been a jackass many time, so for that I put together a startup/shutdown list. It's a Word document & attached, hopefully; if not, PM me w/ email address and I'll send it. I laminated the doc and it sure has helped.

My first jackass move:
Backing out of my slip only to discover that the yellow cable stretched out in front of my boat was my electrical cable. . . which of course was still attached to the dock power pedestal.

Yeah, I've done the power cable pull out, also recently dropped the hot end of the power cable into the water, and pulled out w/ one of the lines still attached which was not untied by one of my buds who was supposedly handling that operation.

If I do anything that means "don't start me", key comes out of ign. Tagouts good idea too.
Not a fan of sea water flow alarms, seen them fail due to fouling. Either not actuate at low flow, or actuate when flow is good. Neither good. Delicate moving parts in sea water are hard to make reliable.
My fave is a snap disc switch on exhaust mixer. Or a look over the transom for water spilling out the tailpipe. I understand the OP can't make that check, and that's unfortunate.
A dive in the ER and put hand on back of pump. Cool, it's pumping. Hot, it's not.

I solved that problem years ago the only time they get closed other than when I excersize them is the beginning and end of the season.

Bwahahahaha you really did that?
Just kidding. I did it only once, but it was the time when I took a dozen folks from work for a three hour tour.

What??? I can't believe you did that....I never did that! I can say that b/c nobody saw it, so it didn't happen.

Best solution: Yell an expletive and add "Can't you follow a simple order!!"
Everybody will think you're yelling at your wife even if she isn't on the boat!!

Do that and if your wife is aboard there just might be a "Man Overboard" exercise sooner rather than later.

Of course the best course of action is to prevent that from happening again.
But just in case everything would go wrong another time (not that I'm wishing it to anyone, of course!), it would have been better to turn on the engine again ASAP after opening the seacock, rather than wait 10 minutes.
The sooner the pump/heat exchanger/engine can cool down, the better.

It should be at the top of a do it ASAP list all by itself. Because it's pretty much a given that you F-ed up the impeller.

I never close my seacock for the enigne or the genset. I don't know anyone at my marina that does.
And as soon as I styart my engine or genny the frst thing I do is look for water out the exhaust. Just habit.

Ditto
If I would close them, bad things are likely to happen.

That would be me. And I do it because I burned a pump and warped a head on a Chrysler 318 once by forgetting. A man's got to know his limitations.

Indeed .. Habit. As soon as my engine starts I set the idle for 1000rpm and head aft. I look at the water coming out the exhaust pipe until I'm convinced it's a normal flow. My lift muffler stores up water for up to close to 10 seconds before it belches out quite a bit of water. I runs w just a trickle and then kinda upchucks. So I watch the discharge for about 20 seconds or a bit more until I'm convinced all is normal.
As for alarms and tags one dosn't need them for cooling water flow. It's such a habit I don't see how one could forget.
My favorite alarm is the Murphy Switch. It senses the coolant water level and sounds an alarm when it's low. And it does it before there's even a slight rise in coolant temp. Saved our bacon once. And our engine has never been overheated.
I do intend to put a flow sensor in my seacock to pump hose.
Jay I've been off and on about closing the seacock but now that we live 30 miles from our boat I'm going to make sure I get that habit too. Those things can sink your boat. I wish there was a lever so I could close it w/o pulling up the engine hatches. Having no rugs it's a bit easier than many but still easy to let slide. I had a bit of a wake up call about water ingression changing a sea water impeller. Went to the NAPA store to get the new impeller and when I got back sea water was up to the top of my engine mounts. Had a boat sinking exercise and got off scott free but I almost sunk the boat. I just assumed the seacock didn't leak. Perhaps I could make another assumption that would sink my boat and a closed seacock isn't total insurance your boat won't sink but I think it sure helps. By the way we just installed a new seacock. Now all I have to do is close it. Opening it is habit.

No, I can actually R&R the strainer and only a little dribbles out unless the boat rocks hard to starboard.

I'm 90 miles away. I never have worried about that
