Chapter two. 

 

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.
