Don't count on that, as I wrecked a raw water Atomic 4 back when I was
a newbie by forgetting to open the raw water seacock. The impeller
will shred rapidly, clogging your block, which is to be avoided. My
solution was two-fold: put the engine key on a carbiner and hang on
the seacock handle (I keep it closed because I've seen two boat sink
at dock from hose failure). The other method is to install a hot-water
alarm that goes off if the manifold water gets above a certain point.
Same idea as a low-pressure oil circuit: a screeching BEEP will make
you switch off the engine first, and figure out what's died on you.

Oh, yeah, I watch my dials and stick my head over the transom now a
LOT more. Expensive and time-consuming mistake, but I was too new then
to avoid it.

Checklists.

As a pilot, I deal all the time with mistakes that are easier to make than
that and can ruin your butt as well as your engine.

I'm going to goggle temperature alarms right now though. The nice thing
about a boat is that you can just buy something like that and install it.
FAA paperwork makes it almost impossible to add any kind of safety device to
an airplane that wasn't included when it was built.

the 'key on the seacock' thing is a good idea. My Yanmar doesn't have
a key, I look for the water out the exhaust.

Wow, you mean I can steal your boat by casting off and punching a
start button? G

If not a key on the seacock, then hang a GPS, your "sailing hat", a
pair of sunglasses, whatever. The idea is that you are persuaded to
check the seacock before you fire the engine, if, like me, you have
irregular visits and don't care to leave it open.

I close every seacock on the boat, by the way, excepting the cockpit
scuppers, which are pretty massively clamped at the hull ends.

Yes. You could also steal it by sailing away.

I keep all mine closed too. After closing the engine seacock, I leave
the engine house cover off whch reminds me to open the seacock when I
return.

Nice. Whatever works is good. Two boats sunk at dock in five years in
a 200-slip club here, one with a failed clamp at the head inlet, the
other with a failed hose at the raw water inlet. Both skippers got the
phone call: "dude, I think your boat's sinking..." Both could have
been prevented with closing the cocks when off the boat.

Say, what about rigging a limit switch to the seacock lever and hooking it
up to a loud alarm that goes off if the starter is engaged?

That would work, but it hasn't gotten to that stage yet in my mental
deterioration G.

Be a lot easier and cheaper to write yourself a note, a big note.

We have In and OUT checklists for opening the boat and leaving it.
They are laminated in plastic.

Seacocks are part of the checklist ritual. We have never forgotten
them.
