Control Cables and Switches



Old Throttle Cable
Cable Damage
When we bought Moonshine the starboard single lever control was very stiff, after investigation this was narrowed down to the throttle cable being worn.  This was replaced with a new 33C Morse Cable earlier last year, which returned it to a nice smooth operation.
Now that we are catching up on the mechanical side of things, we have decided to change the remaining cables as they are all original.  The port throttle cable was removed and was found to have been rubbing on the charge air cooler, which has worn through the outer sheath and corroded the steel wires.  When the new cable is installed we will sleeve it with some rubber hose to help prevent this damage in the future.  The removed cable has now been measured to ensure we have the correct length for replacing.

The fuel valve control cables were removed and measured for their replacements as these had also become stiff with age. 
Next month when Moonshine is lifted out of the water, the gear cables will also be removed, measured and replaced.













After owning Moonshine for the last year the saloon lighting switches have been a petty annoyance, as they appear to have been wired randomly with no method to the layout.  Ideally we wanted to alter the wiring and keep the existing switches.  However as you can see from the above photos, the fixing screws are concealed behind revolving covers of which the inner covers are impossible to remove without damaging the plating.  Therefore a new 6 gang flat stainless steel switch has been purchased to replace the old switches.  The footprint of the new switch is a lot narrower, but fortunately we have a small piece of cream vinyl (from the cut out of the aft cabin port hole) which is just big enough.  A trim piece will be made from paxolin and covered to match the surrounding vinyl and the new switch will be mounted to this.  Photos to follow upon completion.
