Engine temperature

Postby NorWyn » Sun Nov 03, 2019 7:23 am

Hi all,

Does anyone have information on what engine operating temperature is (or should be) at various RPM for the Volvo Tamd 41pa?

Oil pressure stats would be welcome, as well, if available.

What is your own experience?

Thanks guys!

My numbers are within the range Bruce gives for temperature but oil pressure is up around 85 - 90 consistently and has not changed in two years and 650 hours of operation, since we got the boat in November 2017. The mechanic who surveyed the engine was unconcerned about the pressure number.

Temperature varies and rises with higher rpm but at 2000rpm is consistent at about 185. We just got back from a fantastic week in Hotham Sound/ Nelson island / lasquiti area. The Boat is running great as far as I can tell but I was monitoring the gauges and was curious.

(It may be the gauges are not totally accurate).

I am planning to drain and replace the coolant and swap out the impeller this week. Not sure that should make any difference but needs doing regardless.
