It has been proven that water temp gauges do a great job of telling
you when it is already too late. No joke, usually the damage is done
unless you catch it very quickly.

There are two different sensors that can alert you in time: The first
is a raw water pressure sensor/alarm installed downstream of the raw
water pump. The second is a temperature sensor/alarm at the exhaust
elbow. Either or both of these give you enough warning time to shut
down before damage occurs. Many modern engines have both.


A lot of folks don't glance at their instruments often enough. In bobs
case, a gauge or horn probably would have alerted him to problems. Also
the steam coming out the exhaust usually foretells engine damage.
Misfiring or backfiring could also be a warning sign. Or if the engine
slows down without any other signs you might be experiencing engine
seizure. I'm not trying to scare bob, but he needs to pay attention better.
