Following excerpt is from Passagermaker Magazine May/June 07 Written by: Steve D’Antonio Vice President Zimmerman Marine Technical Editor Passagemaker and Ocean Navigator Magazines. If you’ve never experienced an overheated engine, you probably haven’t been boating long enough. As the manager of a busy boatyard, I see the results of overheated engines and gensets all too often. Shouldn’t the overheat alarm tell you when the engine is overheating? Yes, but by then, more often than not the damage has been done. Fortunately, there is a solution to this problem. Borel Manufacturing offers a device that quickly identifies a rise in wet exhaust system temperature before damage occurs. Their Raw Water Failure Alarm is simple, straightforward and easy to install. It utilizes a small, highly sensitive temperature sensor (a fast-acting solid-state thermistor) that is strapped to the exhaust hose. If the thermistor senses a temperature above 165F (well within the exhaust hose working temperature range) the alarm sounds, and the operator can shut down the engine before any harm is done. It does not matter where the water failure occurs- the intake, raw water pump or exhaust injection hose. A boatyard technician installed Borel’s Raw Water Failure Alarm in just a few hours aboard Growler. (36ft lobsterboat owned by Bill Parlatore Editor in Chief of PM Mag) The Borel alarm will work with any wet exhaust propulsion engine or genset.
Easy to install nylon coated stainless steel band sensor with fast acting thermistor sensor.  Fits exhaust hoses from 2" to 7".  Supplied with 10 ft of marine grade, tinned cable.  See optional extension kit for exhaust hose larger than 7".  Call for larger cables lengths.	Backview (single alarm): labeled terminals for easy installation. All electronics potted in epoxy.

Raw cooling water failure is one of the most common problems of marine engines. Within a short period of time several thousands of $$ in damage to engine or wet exhaust system can be caused. Fast acting thermistor, clamped to wet exhaust hose, quickly detects loss or restriction of raw cooling water well before any damage to engine or wet exhaust system. Band sensor's thermal time constant is less than 12 seconds between 70 to 170F. Alarm will sound before engine overheats from lack of raw cooling water.

WHY STANDARD ENGINE OVER HEAT ALARM IS NOT ENOUGH By the time engine over heat alarm activates, damage may be already done.  This piston soft seized, breaking two compression rings.  After a costly repair this customer now has one of our Raw Water Failure alarms on his vessel.

IN THE REAL WORLD. A few seasons ago the sea strainer on our fishing charter boat clogged with kelp. The result was a burned up wet exhaust system that almost caused the lost of the boat. After thousands of dollars in repair and lost revenue from down time, we added a Borel raw water alarm to the new installation. This season we experienced the same problem, sea strainer clogged with kelp. The results however were quite different. The raw water alarm when off so fast we had no damage to engine or exhaust system. Even our raw water impellor was saved. After cleaning out the strainer, we were on our way. All of your charter boats are now equipped with this alarm. I highly recommend this product. Capt. Joe. K. Eagle Charters, Elfin Cove, Alaska (Click here for other customer comments.)
