Garmin 740 mounted above the pedestal over the binnacle
Tie-wrapping of harness and transducer cable
One of most stupid things I did last year was to not run the transducer cable up through the pedestal and binnacle while I had the behind the engine compartment opened up and was working on the muffler and rear drain hoses.
LESSON LEARNED: Think ahead and try to anticipate the needs of future projects so that you can plan better their approach rather than going to extremes with creative ideas.
Hardware inside the pedestal is tight because the steering is done via a vertical chain leading to a cable system to steer the quadrants leading to the rudder. What I decided to do was to cut a 1 1/2 inch hole through the cockpit floor and run thick walled PVC pipe up to the binnacle. Hey it's my old boat, not yours! I did in in such a fashion where I could permently seal the pipe through the floor but disassemble it in two places above the floor of the cockpit for when I needed to gain access. I then cut some plexiglass and tie-wrapped it to the stainless steel support holding the cockpit table wedging it nice and secure. I then hooked up the Garmin to the plexiglass and connected the cable emanating from the verticle PVC pipe. When not in use, just push the cable into the pipe and cover it. Went back to the transducer, added the polypropelene to the transducer overflowing the angle flange and gently lowered the transducer into its pre-set positioned. We now have replaced the knotmeet (which I left in the throughhull) and depth gage.
