A seawater flow sensor may be more effective.

If you know you've got lots of cold seawater flowing in the system ....

I have a Borel system that was very easy to install. It also has 2 high water alarms and 2 water in fuel sensors. Really like it.

I too like the Borel exhaust temp sensors and alarm module.

High exhaust temp covers 99% of the potential raw water related overheating issues and I can't think of the other 1% but I threw it in just to be safe. It is entirely electronic, so it does not depend on a mechanical flow sensor like the Aqualarm that can foul and fail open.

The Borel alarm system is a simple signal to ground to alarm, so it can be used with any other sensor in parallel with Borel's exhaust hose band. For Cummins 6BTAs which have a fluky stock coolant water overheat sensor location, it can be used in conjunction with another coolant sensor mounted in a place that will be quicker to respond than the stock one.

I believe that Ski uses something similar, although home brewed I think on his Cummins.
