Mercruiser 4.3LXGENII Normal Engine Temp?

[kram66]

I have a "97" Mercruiser 4.3LXGENII that averages about 180-185 degrees when run hard......Ive never seen it above 190 degrees.

Is around 180 degrees typical for this engine?

Ayuh,........

If it's Raw water cooled,.... It's running a tad Warm,+ I'd change the Impeller........

If it's Freshwater cooled,....... That sounds about Right.........
