        Looks like an elegant solution to well documented problem. The only
potential problem I can see (and the LAA might object to) is that it
uses an electic water pump and this makes it dependant on the
electrical system. With a belt driven mechanical water pump
(automotive practice) this could work.

   Hi, 
  This is my first post, I hope it works!  I'm posting this to the
Europa list rather than the Jabiru engine list because the Jab 3300
getting too hot seems to be a specific Europa problem, even listed on
the LAA's approval document as an issue! 
  Anyway, I have been looking at the ROTEC LCH (Liquid Cooled Heads)
and I think this is a really interesting idea, bringing a key feature
across from the Rotax engines.  They claim that in an hour of ground
running at WOT the heads only hit 200 degrees! 
  Here's the link: http://www.rotecaerosport.com/product-info/lch

  I'm posting on here not to spark a "Jabiru vs Rotax" debate, we all
know how that debate goes, I'm simply looking for people's thoughts on
this idea.  Technical and otherwise. 
  My other particular line of enquiry is how likely this is to get
Prototype Modification Approval with the LAA, how onerous this will
be, how much down time the aircraft is likely to have as a result.
