By amazing coincidence, I just happened to have replaced my old DataMarine original speed and depth in the last few weeks. While both still worked, the display numbers were getting so weak to read, it was time. Also, I wanted to get modern instruments, so the data could be posted onto my SeaTalkng NMEA 2000 network to post on the chart plotter, calculate true wind vs apparent wind, etc.
It was not too bad a project. I had traced the wiring to understand how it ran, to insure running new wires was going to be possible. I used one of the old transducer wires as the messenger to pull through the new wires. The route (as you probably know) is....... Transducers in the forward area of the U-Dinette, then back beside the starboard water tank, then under the ice-box and the stove, under the aft locker, then a right turn along the front of the holding tank under the aft berth, then a right turn along the starboard side of the engine mounts, then up the front of the engine compartment, and behind the stairway aft-facing plywood, and then a short run between the cockpit hull and the inner liner. Using the existing wiring as messenger made it pretty easy (don't loose track of it ! or break the connection between the old messenger and the new wire). Fishing around with a contractors, fishing wire thingy (what do you call that thing), was not terribly productive and might take forever.
I was concerned about whether the old transducers were installed with 5200 (the BANE of all mankind ! ), but they were just installed with traditional Life-Caulk . (THANK YOU O'DAY !). I did make the job easier by pressing them out from the inside with a small bottle-jack and they came right out. Not quite like butter, but not bad at all.
Attached are some pictures.
The new instruments are Raymarine ST50. Love them!
Thanks for putting this out there. You did exactly what I was trying to do but my wires won't budget... I pulled and looked and pondered.. pushed "fish" sticks all over the place and still nothing. BTW you are correct ODay made it easy... but I used 5200 on my new one.. I hope I don't live to regret it 8)
Enjoy
