Question about Raymarine St40 Depth Display E22038

Raymarine St40 trouble

I helping a friend install a second depth finder in his 42' sea ray. He currently has a transducer hooked up to his Navigator system, but wants a second one as a back up. We plan to cut in a raymarine ST40 but I am wondering if they will interfer with each other. The existing transducer is a 170K HZ. Not sure what the ST40 comes with yet.

We plan to mount the new transducer about 15' forward of the existing one is this far enough? or is there nothing to worry about?

50/200 combination will work fine but 170/200 may be a little close in frequency and give you some trouble. "May be OK" doesn't leave me with a lot of confidence.

How can I stop spontaneous anchor alarm


The anchor alarm tolerance may be set too tight. Ray marine has an extensive library on-line. I have usually been able to find what I need there. May take some digging though.

Why does my st40 bidata read a maximum 1.3 knots in any conditions. I have checked the paddle wheel, it is running free and all 4 paddles are in place?


Even the smallest amount of friction can keep the paddle wheel from turning properly. See if it will turn if you blow on it. If not, there might be something impeeding it from turning easily.

Is it posible to conect garmin 420s gpsmap to st40 deth transducer


No. St series from Raymarine are made for digital depth only, not fish finding and do not talk nmea. The only way to get that Garmin of yours to see depth would be to go from an ST40 nmea out to that garmin nmea in. Or purchase a nmea 0183 smart sensor and hook it to the garmin.

Hello, our Raymarine ST40 depth sounder on our trailer sailer has stopped working only shows 0.00 depth on the display screen. However the metres symbol now flashes on/off. I have checked the cable...


now there is a chance that the transducer is bad ,, but I would check the battery voltage and make sure you have a soild 12 volts to the unit. also in my many years of working with and installing these units on boats I have see the needle pins ( where the plug inserts in the back of the display unit ) bend and/or break off completely. look in the plug area of the display unit and make sure all pins are intact. one more place to look for the problem is in the plug itself, take the plug apart and inspect the wire connection and make sure they are all good. if after all the above has been checked then I would assume that it is the transducer itself.
if you have anymore questions with this problem, please feel free to write back and ask,

My raymarine ds600x is losing bottom at 120 feet...water temperature is at 220. I have a thru hull transducer...Im wondering if my ducer is fouled up with marine growth or is it a bad ducer or head unit.....


The depth loosing bottom would certainly indicate that you may have growth fouling the transducer, however the sea temp 220 degrees indicates possibly a different problem. Start by being sure the transducer is squeaky clean and see what that does for you.
