I have 675 KEs. Today I did a few 120+mph runs @ 5,800rpms for testing and saw the oil temp go up to 260 on my starboard engine. The temp gauge was still at 140 and the water pressure was at 12 lbs. Scared the hell out of me. It never happened before. I checked the oil level afterwards and it looked good. I am using Mobil I oil. Help needed, any suggestions?

What does the oil temp usually run?and the other motor?

Spectre Man

Both engines generally run at 140 degrees. The needle never moves off the bottom line. I checked the oil and it was like new and exactly to the full line. The oil pressure is a solid 80 PSI. Water temp is always very low (100 degrees).

Couild it be a defective oil filter?

Might want to back flush your oil cooler, or at least pressure check it.

Not much to add here but, what was the water pressure earlier in the run? What does it run historically? Did you pick up some weeds,etc. What's in the sea strainers?You said the water normally runs at 100 degrees and the oil at 140 degrees. Aren't these low?

How do you back flush th oil cooler?

Take the water line off both ends and have at it!!!!

I am thinking your oil cooler is not getting good water flow as well.
