Hot Engine Oil
I have a 95 Nordic 28 heat with an engine oil temp gauge. Running a 468 bbc and the engine oil is around 300* (give or take 10* Is this normal? The engine temp stays right around 160*

engine oil ???? don't think so....thats a little to high..depends on what you have been doing running hard for long time....mine would get to to about 280 after running hard..did find the wrong 11psi valve in the block(gen VI) they say that will make a big diff putting the 30psi one

The Mercury 525 service manual puts the max at 220* so I would start to get concerned about that temperature. I don't know anything about a pressure valve but it sounds like the oil cooler is not working. Do you have an oil thermostat? Could the oil cooler be plugged?

Gen IV block, 468, not run that hard 4200rpm for about 30 min, It is in a 95 nordic 28 heat. Oil filter is on the motor. It has the bolton/spinon oil filter adapter. I have an oil cooler mounted on the stringer that the sea pump flows through first before going to the block. It gets feed from 2 lines dirrectly above the filter. No oil thermostat. Just added the oil temp gauge with the sending unit in the bottom of the pan. Also it is a dooley 14qt oil pan.
