T-stat or not T-stat...

On raw water cooled engines, they fail both ways about equally.

Ive had a 2002 and a 2005 vehicle that stuck closed recently. Never heard of a stat built to fail open, its a good idea though.

They didn't happen to be Subaru Outbacks did they??

Stuck T-stats are an almost instant killer of those 2.5L engines. Overheat just a little...heads are shot.

Seeing, reading, and hearing all of the problems associated with overheating, due in many cases to faulty T-stats.

almost never on boats

90% or more overheats due to impeller issues. imho...

You can make your own over-temp alarm.
Here is what I did:

The main component is the temp switch.

I don't believe oil pressure alarm is that necessary.....just my opinion.

Yes, but the oil pressure switch will fire the alarm every time you turn the key on to start the engine... An EXCELLENT self-test of the system... You hear the alarm, you know it's working....

This is also, just my opinion...

If this is for the 165, there MIGHT be a hole in the water pump, but otherwise, yeah bang another port in the thermostat housing....

Yep...just checked. There's another port right next to the temp sensor. Good call!

Which is very obnoxious by the way. I want to design one and build one that has my stupid drunken ex-wife yelling the faults at me!... No probably not a good idea if I have any weapons around.

Well,

If you want to "ex-wife" proof the boat....just put a normally closed relay in the oil pressure alarm circuit and wire it to the ignition.........

When the oil pressure or temp goes awry, it'll interrupt the ignition and kill the engine......just don't let her drive it near any waterfalls or spillways......
