My 914, s/n 4417778, matches the Rotax Installation Manual's illustration of
the silencer, which is the same in the Europa supplied 914 manual, viz., the
size at the exit end of the round tapered tube on the silencer is 38mm ID
and 40mm OD, and there are no slits. With a 30mm OD stub it does look like
a large gap but I assume that the factory folks know what is right. The
slits are on the silencer end of the EX06 tailpipe.
A quick check of the Rotax web site
http://www.rotax-aircraft-engines.com/aircraft/aircraft.nsf/index?Openpage
reveals that my installation manual and the latest version on the web show
the same details, suggesting that Rotax did not change anything. Obviously
something has changed, however, and I suspect that the folks at Europa may
not be aware of the change.

Subject: Europa-List: Exhaust stub
<paul-d.stewart@virgin.net>
The 914 engine installation says to TIG weld a stub into the tapered
silencer outlet to allow the down pipe to clamped on. The silencer on my
recently delivered engine does not have a tapered outlet, rather a parallel
sided on with 4 slits on it. The piece of stub pipe is significantly smaller
than the outlet and will require a large amount of weld to fill the gap. In
addition the slots in the silencer outlet would appear to also need welding
up as they are longer than the stub. If this rambling means anything to
anyone can you tell me if this is a correct state of affairs.
