After impeller and thermostat, engine is running at the proper 140 degrees.
Starboard riser still hotter than port enough for concern.
So I call Mercruiser and they answered the phone!
Further the lady answered all my questions with grace and expertise!
Turns out that a hotter Starboard riser is designed in and normal.
She said if you can keep your hand on it, its ok.
I guess its ok then.
Well the boat needed all that was done to it, so time to clean it up.
And that is the end of the story - hopefully.
