cheap temp gauge

[charliehows]

i been worrying about the operating temp on my raw water cooled yanmar 2qm20 - the original engine only had a temp warning alarm but my boat has a temp gauge which has never worked...I was browsing in a commercial kitchen supply shop the other day and i came upon a cappucino milk temp gauge running from 0 to 100 C with a blue zone around 60 for when your milk is the right temp...the yanmar should run between 50-60 C with the alarm set to go off at about 62 C.
$10 and a bit of tape to stick it on top of the rocker cover - instant peace of mind. Makes good coffee too.

Sorry, I though I was responding to a boater

Why waste money!! Lucky for you temps over 60 C also correspond to skin blistering. Just grab hold of that bad boy and if you blister up in 5 seconds you're runnin hot . Not a penny wasted!

Charlie,

Reminds me of when my girlfriend's Nauticat overheated on a trip out to the Channel Islands. I checked the strainer, tested the thermostat and removed and cleaned the heat exchanger before I thought to stick a meat thermometer in the coolant. Turns out the guage had a bad connection. Overmyhead's solution would have been simpler still!
