I have had issues periodically with i60 depth display readings. This was alleviated when I ran that transducer cable away from other cables.

All kidding aside, I have been going through some interesting things with my transducer as well . It is not the same, it is electromagnetic, but it is also airmar. For a period of the summer I was getting readings like 140 150. Then they would change to somewhat more normal. I found that unplugging the n2k cable, and then plugging it back in again, sometimes helped. Eventually, about a month ago, the readings came to near normal around a three degree adjustment on my part. I have no idea what could make it do these crazy things.

I just don't know what condition the through-hull is in given we've never removed it and I doubt the previous owner had done it in the past decade as the boat had been sitting on the hard for the past 5 years prior to this summer. Does nobody think the temperature reading is abnormal?

Suprisingly little water comes in with the ST60 speed transducer removed. Process is 1. Unscrew the retaining ring, 2. Pull out the transducer, 3. Screw on the plug in place of the transducer. Takes less than ten seconds and not a lot of water comes in. Transducers foul by this time of year and require cleaning. Likely the boat has been in the water for a number of months and the water has been warm. This is pretty normal.

The speed sensor reported 0KTS during survey. I cleaned the paddle and it turned free during survey haulout and the instrument worked fine for several weeks after that. Then, the speed returned to 0KTS but the temperature read fine. I casually brushed the paddle while in the water (not brave enough to pull it out while floating yet, want to try in on the hard first. No idea when the last time this was done) and it was no help. Last weekend the temperature suddenly doubled reporting about 135F seawater. I lifted the instrument and measured resistance across what appears to be a 10k thermistor and it correlated well to a 10k chart suggesting water temp at the marina was near the expected value. Am I jumping the gun to assume the display has gone bad given the temperature sensor seems like it is working or should I check something else?
