Engine water flow alarm

Bill Seifert in his book "Offshore Sailing" recommends the use of an aqualarm (Tip 128, page 100) to monitor the flow of enginee cooling water.

I have never used one of these and would like to know if anyone has experience or opinions on these. My engine is a Volvo MD2B raw water cooled in aa LeComte Northeast 38. This is a 2 cylinder diesel producing about 25 HP.

We surely need something like that in our old-fashioned North East 38s! Our exhaust is under the long stern overhang (about 7 feet!), so we can verify water flow only at a calm anchorage. I don't propose to move the outlet.

Perhaps an exhaust temperature guage?

I just Googled Aqualarm and found that you can buy a toy for $325 or so that monitors oil, water flow, bilge, fire, and 'high energy' whatever that is. Gosh!

Here's a solution... a little klugy, but its what the PO did on my boat and I've kinda grown to like it.

If you make a vented loop for the engine cooling water before it hits the exhaust mixer, attach a hose to the vent and run it to the cockpit just over one of the scupper drains. When the engine starts and the raw water makes its circuit, some will be diverted through the vented loop into your fitting in the cockpit and it is very easy to monitor the flow right there. Let me know if you want to see pictures.

I think I am experiencing deja vue (spelling?)

I didn't know how to easily put the accents in there.

Showoff.
