Oil Temp ???

Getting ready to run a new 502 engine in my 25' Outlaw----picked up a oil temp gauge today.....was told I need one---The sensor is installed into the oil filter bracket (Hardin Marine) !!!!!! The oil line into the oil filter bracket comes from the oil cooler....Bottom line--WHAT temp am I looking for???? I never had a Temp gauge on my boat-nor seen one on anyone of my friend's boats !!!!! .......I have searched many forums/ with all different answers, depending on where the sensor is located ????
Thanks---Mike--Tampa Bay !!

In the most general terms the oil should get hot enough to steam off the moisture that accumulates in the oil. So somewhere near 210. Most would agree 280 is too hot and 150 is not hot enough.

Thanks again----The gauge is in and I hope to put her in the water this week......

Good luck with it. I liked the way Jim put it.There have been a few times when my oil temp went over 250 and that's when I shut down and started trouble shooting.

Thanks----I have never had a oil temp gauge--nor any of my friends boats---SOOooo it is a new learning experiance !!!!! Mike-Tampa Bay !!!

The second biggest advantage of having an oil temp gauge, you will not believe how long it takes the oil temp to come up to 100+ where it should be before you drive it hard......

Yep, it sure can take a while to heat oil when you live so close to the polar ice cap. LOL:rofl:

He and I boat in warm water. Our oil starts at about 85. :sifone:

OUCH!

Well the good news is there are thermostatically controlled oil systems available for our northern buddies. All Mercury Blue engines now come with them.

The oil warms up, just takes a bit of time.....
