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

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.
