    Teflon Liner with .250" flex shaft

    Hey guys,

    My apologies, as this surely has been asked before, but ive done search after search and for some reason, the criteria is just too broad and im having trouble guidance here.

    How exactly does a teflon liner work with a 1/4" flex shaft, as far as the strut setup goes? For example, im used to having the stuffing tube be a piece 11/32" brass tubing glassed into the hull, and then 5/16" tubing running the length of the flex shaft and all the way into the strut, with the bushing riding inside the 5/16" tube.....

    If I have 11/32" sized tubing replacing the 5/16" in order to run teflon inside, how does subsequent strut setup work??

    This also leads me to another question, as I seem to notice alot more people overseas in Europe using teflon with the bigger flex shafts.... Im curious as to why the struts made over there, for example, the ones sold by MHZ, include the drive dog and prop shaft as part of the strut assembly???



    Thanks !

    More than likely you are running 8s or 10s using this size flex cable ?
    Personally I would stay away from using Teflon with 1/4" flex. Use the 5/16th brass, it will fit right into the Speedmaster strut.
    Nice smooth bends on the brass, grease the cable and you will fine.

        ill be fine?! gee thanks! load of weight off my shoulders!

        As I originally said, it seems alot more people overseas seem to be running teflon with the bigger flex shafts. Iits been abundantly clear to me for a while that majority people here prefer to ditch teflon with 1/4" flex shafts in particular.

        I was asking how teflon can be used on a 1/4" flex shaft, simply put. Whether this is for hypothetical reasons, or for my own setup, or because im simply curious, is irrelevant and was never acknowledged in the first place.

        But thank you, nevertheless.

        Very interesting, you fabricate these yourself?

        Can you send me a private message with more information please?
