Tom, do you have any idea what the temperature of a riser should be on a warm
5.7L Mercruiser? Should there be a difference in the temperatures of the two?
The mechanic at my marina told me the starboard riser will run hotter than the
port. Any knowledge of this?

No, although the engines I've seen serviced by shop technicians
usually run between 90/110º - anything above 130º is considered
suspect but that's not an official temperature - it's just an
observation on my part.

As to differences between risers, I'm not sure why that would happen
and would love to hear if there is a difference and why. I've never
heard anything about a difference being normal.

Take care.

Tom
