Replacing 22 year old Autohelm ST50s - Callisto - 11-07-16 11:02 AM One of my trusty Autohelm ST 50s (the tridata I think) is shorting out and tripping the breaker that the instruments share with my newly installed e-97 chart plotter (hybrid touch). I have isolated the instruments in the circuit and eliminated the breaker tripping. Now I think that I am faced with replacing the instruments I installed 22 years ago. I am planning on installing an I50 tridata and an I60 wind instrument (I need two instruments in that rectangular proportion to fit my helm station). Questions: 1. Should I pull all new wire or just replace the ends on the wire that is in place with the new plugs. 2. Will the new depth/temp transducer and the new speed transducer fit in my existing holes/threaded sockets in the hull or do I need to haul the boat and change the thru-hulls? RE: Replacing 22 year old Autohelm ST50s - Chuck - Raymarine - Moderator - 11-09-16 05:57 PM Welcome to the Raymarine Forum Bryan, Q1. Should I pull all new wire or just replace the ends on the wire that is in place with the new plugs. A1. While the i50/i60 instruments have been designed to be installed as replacements for ST50+ instruments, they have not been designed/tested to replace ST50 instruments. Accordingly, it is recommended that new power and communications wiring be installed to support the new instruments. Q2. Will the new depth/temp transducer and the new speed transducer fit in my existing holes/threaded sockets in the hull or do I need to haul the boat and change the thru-hulls? A2. The currently offered P800/P17 and B17 housing based depth and ST800 housing based speed/temp transducers continue to require the standard 2" [censored] commonly used by transducers which had be offered for use with the ST50 depth and speed/temp transducers.
