    Default engine oil temp

    What kind of engine oil temps is everybody happy with. Right now, mine is running around 200 degrees cruising at 35-4000 rpms, and 220 degrees at wot 6000-6100 rpms. Engine is blown sbc on pump gas with an engine oil cooler on it. Temps just seem a little high to me.

    Thanks, Ryan

    Actually your temps are about right. Oil always runs hotter than the cooling water.

    Without knowing more about your combo (oiling/cooling system and plumbing, running engine water temp ect.) it's hard to say, but it sounds a little high with an oil cooler. The listed temps are nothing to be afraid of as long as your using a good synthetic oil but............?

    I am using a semi-synthetic oil, Brad penn 10-30. The oil cooler is plumed right off of my jet pump, the water then goes into the engine block, then out the boat. The temps I am seeing are on the high side of the autometer guage I am using.

    Those are great numbers. You need your oil to get hot enough at points, like 220, to burn off any condensation suspended in the oil.

    Ok, sounds like the general opinion is that the numbers are good. I am glad to hear that. Thanks for the help guys, Ryan

    Sounds safe, but I agree with that Warp guy...for something with a cooler maybe a little high, especially at cruise. What kind of clearances and oil are you running? Might want to try another gauge to be sure. I wouldn't call them perfect.

    Mine is plumbed the same way, I open and close the valve down to raise or lower the temp. Can you open the the valve a tad to feed it more water.

    Yours is just a tad higher than ours I run it at 180-190* on long cruises at 4,000 and it runs 210-220 after some power passes.

    I can open up the gate valve some more to let more water through it if the temps are a little high. Next time I am out I will check the oil pan temp with my infared temp gun to see if the guage is somewhat accurate.

    Pump to oil cooler to engine. Engine oil temp is running 180-200 cruising, 200-220 running hard. Engine temp never seems to get above 180, usually 160-180.

    If you would what do you consider a long cruise at 4,000 in minutes. I run a 29' vee and 4,000 rpm cruise is common. I had v-drive cruiser and 4,000 in the 29' vee is more strain on the motor then the v-drive had.

    I run a Olsen cooler the 15" and oil temp will climb on long runs. I do not like cutting my runs short because of oil temp but better to be safe then sorry. Trying to decide on plumbing change or bigger cooler or both.

    Thanks Andy
