[C320-list] Water Temp warning light

[Karl Mielenhausen]

Marko,

It would be helpful to know which engine you have.

I suspect your impeller has broken/missing vanes.
Was it inspected this spring before commissioning?
Was it removed during winterization? (They can take on quite a "set" over
the winter, to the point where the vanes fracture upon start-up.)
If the impeller checks out, you may have a partially fouled heat exchanger.
Here are some Mainsheet references to a hot running engine....

changed two years ago with 44 hours on the new one. My intake filter is
clear. I ran the engine for approximate 30 minutes gauge still reading 80c
and then I decided time to shut it down. I let it cool down and then tried
it again hoping it was a temporary thing.
