It's a raw water cooled engine with only a high temperature alarm and
no gauges other than the tach. If I had a temp gauge so I could watch
the trends, I wouldn't have bothered with this thing. In retrospect,
a temp gauge would have been a better choice but I was way
overextended with refit projects and the Aqualarm was much quicker and
easier to install. The problem is, it just doesn't seem to work
reliably.

I'm finding the Aqualarm raw water flow alarm to be a much better
idea
in theory than practice. I'm going to call them soon and would be
like to hear any other experiences.



I'd be concerned this alarm not going off would make someone
complacent to
the engine temp guage going up and not being noticed....

Does your Yanmar have the freshwater coolant recovery tank with the
hose
connected to the cap? The hose under the cap is a PRIME suspect in
overheating. Been there, done that, got the T-shirt. The hose
falls off
and the cooling system sucks in air instead of coolant every time it
cools
off...emptying the cooling system far enough to cause overheating.
You
look at the coolant recovery tank...it looks like it's got plenty of
coolant because it's overfilled, when, in fact, the heat exchanger
on top
of the Yanmar is nearly empty, filled with recovered AIR from the
leaky or
loose hose under that cap. Stupid, Yanmar...STUPID!

If you've got a temp guage and overheat alarm, you don't need this
other
alarm problem going off. Dump it. It's only a diesel engine, not
the
Space Shuttle....(c;
