    Nuetral Safety Switch-gctid399433

    I've been stranded twice now- once on the water and once in the berth because the neutral safety switch is acting up. It's a 1985 Ciera Sunbridge. I can't risk messing around and want to put a new unit in but don't know where to find one. Any thoughts? The problem comes and goes. Dead one day then fine the next. All feedback appreciated. Thanks!

    You sure that it's the nuetral safety switch? Usually if they're out of alignment, you don't start. You'll find one at your Bayliner dealer, or on-line (if you know all of the particulars of your engine). Get a hold of a manual, and you can likely just do an adjustment.

      Thanks! The symptoms are when I turn the key the gauges all come on but no starter. Usually if I play with the shift bar enough I can get it to start.

        Does your '85 have the Morse Twin S .............



        or the Morse U-flex unit?



        The U-flex seems to give us more trouble.

        If memory serves me, the micro switch is different for each, and you'll also see several different configurations for switch mounting.

          Thanks Rick- It's definitely the U-flex unit.

            The U-flex can be problematic.

            The Twin S is a much better unit.

            The U-flex actually has a better neutral safety switch arrangement, but you'll find two styles.

            One uses a detent notch, the other senses cable angle.

            Best I can offer, is pull it apart, and look things over.

            Take a few phtos.

            Adjust, and give it a try.

              So I tried to pull the throttle/shift assemble (picture 1) but because of the way the screws are its going to be in two person job. However, while underneath I tried tightening the "turn buckle" (picture 2) which was loose. It seemed to have improved things. Since this is an intermittent phenomenon there's no way of knowing if this was the root cause or if its fixed but it seemed improved. My question to you all is would be having the part in picture 2 loose be enough to trigger the neutral safety switch?Picture is the assembly found directly behind the mirror in the head.

                OK, the red arrow points to the detent that engages the micro switch. This is actually at the throttle side, but you'll have the same detent at the shift side (curved red arrow down in there somewhere).

                The blue arrow points to the channel section where the micro switch mounts..... actaully, it mounts at the oposiste side (curved blue arrow).

                The detent is rather narrow, and makes it a hair-trigger for finding neutral. None-the-less, this is the part that depresses the micro switch when in neutral.

                  Thanks Rick! I appreciate all of the trouble you go to.

                  I was digging through the 30 year old box of manuals and found the original product guide! The original was a Teleflex CH 4500. A Google search makes it look like this has been deprecated and replaced by the Teleflex CH4400 series. Its listed as a "drop in" replacement. Is it really a drop in? Is it something a Noob should attempt to replace?

                  Thanks again.

                    I would have to guess that the Teleflex CH4400 is the direct replacement.



                    If you don't mind the older style and characteristics, the Twin-S is Tried and Proven and is pretty tough to beat.



                    I rarely see problems with these.

                    The foot print is slightly smaller, however, so an adapter plate must be made.
