oil temp
 

had a conversation with a couple buddys today about oil temp,one of them said the teague hp engines run a max of 160 deg oil temp,both of my boats run 190 to 200 deg,what do you guys run for oil temp?

Oil temp
 

Mike,

I have had 2 sets of Teagues motors. The 1st set and the current set use both coolers on the bell housing with no thermostat. Never any issues with condensation and the motors show virtually no temp on the gauges. Bob does not use thermostats with his motors. I run the cold waters of Lake Michigan.

Mine barely pull off the peg even in hot days, thought they were broken till I saw them move one day. :faint2:

Even running LOTO hot summer air and water my temp gauges will barely move. Heat kills!!!!

190* + - Never a problem with condensation in the oil .

i get 180-200 most of the times...one must remember that cold oil does not lubricate well

I see about 185-195 depending on lots of things, after a LONG run at WOT I may see 200-205, but I don't see that as an issue.

Mine run 180 cruising, 200-205 Firewalled for miles. No condensation. This is with the Merc HP Thermostatic remote filter mounts.

Before I had those thermostat units, Oil temp gauge barely ever moved. On hard runs, maybe 130-140, and took forever to get there. I would get some condensation in the breathers. However Bearings did look new after about 7 seasons on them when we tore down.

I also run the Bellhousing plate style coolers.

FYI, Mercury uses a oil thermostat, on the 600, 800, 900, 1075, 1200, and new 1350.

And anyone who knows anything about engines installed one, right?

I'll be for real, you are "eleventy" levels above what most guys see for power, but that temp is important, where it's measured even more important. You don't need a bazillion dollar motor to know that.

One would think so. I take my temps in the pan.

I'm sure a Builder like Bob Teague, must have a reasoning behind running the oil cold. I personally would rather have oil on the cold side, rather than the hot side, but ultimately, have it at a temperature it was designed to run at. But then again, I'm not Bob Teague, and if I had his engines in my boat, I'd leave the setup up to him.

Hey Gary, shoot me a PM with your email. I think I have a short video of you passing by Michigan City I took this late September... I can email it to you if you like.

Sent you a pm. Send it over to me, Thanks.

send it my way to joe,i havent seen the boat but i hear its sharp

I will. Still trying to send it to Gary, the darn file is too big to email. I need to figure it out.

He was just cruising on by, wish I had more time to zoom in. You have to see it in person, I think you'd be pleasantly surprised.

my cat uses both bellhousing coolers for the oil,but i run oil thermostat and it still takes a while to see 160 deg oil temp,the mercury setup measures temp before the cooler i believe.

I put a Canton oil stat on one motor and it raised the temp from 140`ish to maybe 165*ish and the oil was bypassing the oil cooler.. never saw any differences between the motors, no condensation anywhere

Proper Oil Temp
 

Oil is tested for rating at 212F. In other words single weight 30 is 30 weight at 212F and multiweight 10w30 is 30 weight at 212F. Proper operating oil temperature is about 200F to 210F. Too cool oil will cause extra wear & tear on your engine.:cartman:

Has anyone heard from Teague on the reasons or theory for not running a stat? I would think there is a method to his madness. Or is his cooling system that perfect where it self regulates? I believe it to be highly unlikely but thought I would put it out there.

also on the 500 525 575 700 hp engines.
