Having serviced Poseidons (Cyclons and Odins) since 1978 and being the
defacto New Zealand agent for the last 10 years, I have been aware of the
second stage flutter following service. Sure it's associated with the
silicon sleeve but I doubt if it can be linked with a change in
manufacturer as it has always been an occuring fault. Two sleeves from
the same packet (batch) can perform differently. 99% of the sleeves are
fine. They have changed the part tho. Initially, on the Maximum
(Odin/Jetstream), it was called the sleeve and sleeve holder. Now it is
just the valve insert. I have a thousand of the seperate sleeves, some
of which may flutter!
We also use the winterised Odins in Antarctica. Salt water temp = -1.8 C.
Occaisionally you get small flakes of ice flying to the back of the
throat, but you get used to it and eventually think nothing of it.
