Engine Temp 230 degrees
My supercharged 502s that produce 600hp each run a little hot. After cruising at 3200rpm for 15 minutes, my engines temp creaps up to 225-230. I slow down to idle and the temp drops to 185-190 in about 3 minutes. What is too hot. I use Mobile 1 15/50. Any input or advise?

i had this problm 3 weeks ago, it sounds like your not getting enought water flow, and have you shot it with an infrared gun to see your true temp/. my 1st guess wouldd be water pump if not that water line is getting restricted ( is it both or just one motor that runs hot??)

No infrared gun. Both engines are doing the same thing every since I purchased the boat in 2004 and had new engines built. Water pump impellers have been changed out 3 times. I still don't know if 230 degrees is even something to be concerned about. I never let it get past 230 degrees. The oil coolers are the original coolers from 1994. The boat has always been a freshwater boat. Maybe new oil coolers or a double water pump. Should I spend the money or not worry about 230 degrees.

You're talking about engine oil temps correct? If so I wouldn't worry one bit about 230 - hell if has to get over 212 to burn off condensation.
If you're talking about water temp - good lord....

Oil Temperature, not water temp. If water temp gets that high, an alarm goes off. I had that happen once when the impeller got destroyed while I was running the boat on the trailer. I think I got all the rubber pieces out. Both motors still run the same. Does anyone know what temperature is too high for a superchaged motor.

EDIT - actually there are lots of threads and the general consensus is that 230 isn't bad.... I wouldn't let it ruin your 4th of July.
