Teleflex Engine Control Cables - SO37 and SO37 and others
This article by Alf Morten Granholt is reproduced here in English by kind permission of the Norwegian Jeanneau Owners Club.
Whilst only the SO37 and SF37 produced prior to 2004 are referenced, this issue may also occur on other Jeanneau's using the same design Goiot pedestal such as the SO34.2.
Some owners have noticed the engine teleflex cable binding and creating excessive wear, which is believed to be due to too narrow conduits being used in the original Goiot pedestal design, resulting in a very sharp bend of the cable at the top of the engine control housing. This has even resulted in the cable breaking which can be alarming and dangerous when berthing.
Boats produced prior to about 2004 may have only a 1" (25mm) alloy tube through which the control cable up to the engine control housing is threaded. This was a known problem which as a result there was a production modification made around 2004 when the original smaller alloy tube was replaced with a larger diameter stainless steel tube.

Note that the painted aluminum pedestal casting was also modified to take the larger down tube and "O" ring seal it is not possible to simply fit larger down tubes.
Some owners in Norway made modifications by using a larger aluminum tube that has been "crimped" to still allow the original pedestal base and seal to be used. At the top the tube the housing can be enlarged.
Special Aluminum tubes - after "crimping"
It may be possible to replicate this by sliding a larger diameter tube then bonding it onto a stub of the original tube.
It is also wise to carry a spare teleflex cable in case of breakage. Some teleflex cables are also more flexible than others and will tolerate a smaller radius bend.
