My depth sounder on my '85 28.5 worked fine until recently. It works for a time, then just flashes the depth last recorded off and on for a period of time, then works again for a short time. The manual has nothing described like that in its troubleshooting section. Has anyone any suggestions?

I have the same problem
I beleave the transducer is the culpret, I'm replaceing mine this weekend

Depth Sounder Problems
Hi John, I have the same problem on my 1987 28.5. What type of transduced do you have? Mine is a mounted on the inside of the boat. Let me know if your fix works. I am tempted to buy a new one. Mine is over tem years old.

The depth sounder on our 1991 P42 does the ...
same thing. Our Raytheon manual says that if there is no depth change after so many seconds the last depth reading will flash. Also, when it reachs 800 feet (manual says it reads to 600 feet) it displays under ten feet. Terry

Thanks for letting me know I am not alone.
I suspect the depth is, unfortunately changing. We sail on the Sacramento Delta, an area of shoals and shallows.

bleep deep sounder
My fairly new DS 45 began to fail intermittently. It showed erratic readings or just dashes, particularly in depths under 10 feet. There also seemed to be a weak correlation with wakes from passing motor boats. Standard Horizon could find nothing wrong when they had the unit on their workbench. So I installed a new transducer. This DID NOT fix the problem. A Standard Horizon service advisor thought it might be an intermittent failure of the microprocessor in the DS 45. Whatever they did this time, the unit has worked correctly the last three times out. I now believe that if the unit works part of the time then the transducer is not the likely culprit.

Replace it with a Fishfinder
Last winter, I mounted an Eagle 160 fishfinder in the cockpit bulkhead where my old SR instruments depthfinder was. I sent the transom mount transducer back to Eagle and they exchanged it for a puck mount (for trolling motors) transducer at no charge. I took out the thru hole SR instruments depth transducer and drilled out the guts, then carefully ground the new puck transducer to fit in. Epoxied it in the old SR carcuss, and put back in the hull. It works like a charm, plus gives me some entertainment with fish on the screen, plus battery voltage, etc. all for $129 from Boaters World. Plus it came with a coupon for a speed/ temp transducer. I did the same with it, and it worked until I put it in the hull, so on that one I must have ground to much, but that one would have been the bonus anyway.

Clean It
Our had the same problem and it was due to debris. Pull it after putting transducer replacement and clean it. If that dosn't work check your wires you may have broken them.

Aerated water?
Do you sail where there is a lot of current? We found that when we were in heavy currents or flood/ebb tides, our depth reader would go haywire and take up to a couple of hours to get back to normal. The manual says it is aerated water causing the problem. It would flash the last reading or just show blank lines. (First time freaked me out as we were in an area I didn't know and the charts did actually have a shoal area although when we check our positon and the GPS we were not over it.) Seaweed can also be the culprit and if we are motoring and it happens we slow down or circle or put it in reverse and it fixes it. Checked transducer and it was fine...
