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.
