We have a Yanmar 4 cylinder turbo charged engine of about 60 hp and would like to know the exhaust temperature range we should target when powering, as distinct from the Vetus cooling water alarm we have available to fit which will trigger at a relatively low temperature?
The boat is a Southerly 135(13.5 metres) of about 14 tonnes cruising displacement.
Appreciate your advice.
You will need an EGT meter and data from Yanmar for this. In general, most diesels runs between 450 and 800 degrees F at their injection elbow, depending on load.
