Correct running temps

[Paul_S123]

Just wondered what the usual running temperature would be on a P50 with VOLVO D 12 675's Mine runs at ~80 degrees on idle and ~86 degrees on plane.

Ball park .
85/86 in the Med @24/26 summer sea temps ,with inline 6 MANs similar 12.8 L

That's fine...just seems precariously close to the red on the gauge......which granted, is not the most scientific way of viewing thing.

my d12 715 run at 80 when the exchangers are clean.

If you are worried, buy an infra red thermometer from ebay and measure the temperature of the thermostat housing when the boat is planing. The dash board instruments are not always especially accurate (mine are out by 8 degrees) - more an indicator of "normal" and too hot.

Agreed. Both my gauges are out by several degrees compared to the IR readings. The gun in useful for readings all across the engine as well.

Yep, about the same here, D12 800's running at low 80s cruising, mid 80s if pushing it more, they did go up a few degrees a couple of years ago but a Rydlyme treatment sorted that.
