This product is better than a gauge.


Relitatively easy to install. Given that many boats don't get used that often you never know when an impeller or water hose will give out. This device ensures that a loud buzzer will go off if you have an overheating problem (or oil pressure failure which is far less likely). So if anyone is driving the boat, you just need to tell them to switch off the motor if the buzzer goes off.

An early warning system that works!


The buzzer is loud enough to be heard in most installations. Engine gauges are good- but you must be looking right at them when trouble occurs to be useful. The buzzer goes off right when the problem happens. I like to wire in a signal light too.
