We've tried various combinations but can't get a flow through the calorifier. Any advice please?

Inline pump

Thanks, but that will be the last resort if we can't find the correct locations for the feed and return.
I should mention that it is heat exchanger cooled.

Has someone fitted an inline valve that needs turning on ?

I’ve often thought about adding one to our boat to stop thermal circulation while at rest.

You may just need to find it and turn it on.

Hopefully somewhere easy to get to near a hatch

Thanks but no. This is a newly rebuilt engine that we have just installed.
