Bob should install water temp and oil pressure gauges. Also an audible

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.
