Mine usually runs at 160, but if it is being ran hard under alot of weight and being surfed or run wide open it creeps up between 160 and 165...

Is that normal and ok to run?

My predator usually runs the same around 155-160, I would not think that 165 for heavy load would be all that bad.

If I run it hard for a while it may creep up but it never stays there for long. That temp is fine.

A slight threadjack; sorry, but I been told in regards to various engines that you want to see temps of 180 and above to boil away any condensation, etc in the oil. Any thoughts? By and by my boat runs 160.
