Just got one for the bow. I had it installed by a reputable dealership. The transducer is mounted to my ultrex 112. Everything works fine except When I engage the tm the side imaging gets distorted. Down imaging and sonar works fine. Side imaging works until I engage the prop on the tm. I shot a video of what it’s doing but I can’t get it to post on here. Any help is appreciated.

For video you have to upload to another site to host the video like YouTube and then link to here.
Figure it’s the prop wash it could be picking up. Try taking a picture with phone and posting it.
i will, thanks. i don't know anything about creating a you tube video.Quote:

This is just a screenshot of the video. It only does it with the propeller engaged. Power setting has no effect the pic is not great but it’s the best I can do for the moment

I’m going to say it’s picking up disturbance from prop moving the water. I have used mine so little on SI I can’t remember if mine does that or not. What about if you slow your speed down, does it change any. And if not a big pain next chance you get shoot a good pic of ducer mounted on motor.Quote:

Mount the transducer on the other side of the shaft, closer to the nose of the trolling motor.

What he said ....And tilt the back of the ducer down just a little
I really don’t see anything wrong with mounting. You might try turning it around. It could be picking up turbulence from that mounting bracket. Get it out in front of mount.
Thanks fellas I’ll try that

I’ll try to remember to go down to shop in the morning and take a picture of mine and see if there is any difference. If you think of it shot me a pm in the morning.
A little off topic but I have the same unit with transducer mounted on the transom and am having trouble with it loading my maps. I have lake master maps and when I turn my unit on it will not pull them up. The only I have found to get it to work is go into setting and change map source to unimap, wait a minute and the. Go back and change it to auto then it will finally load? Sometimes it takes several minutes anyone else have this problem? Not trying to hi jack your thread.
Does it say “Loading Charts” in the top right of the screen - or are you not even getting any Chart view at all ... ??Quote:

Here is how I have mine mounted
Looking at yours and mine, here is what I think I would try. Like Snubby said move it further up barrel of motor away from prop and maybe if you can find it wrap a piece of rubber around motor we’re bracket and clamp contact motor housing. I still say it turbulence from something.
Yes loading Charts but it never loads, I have to go into the menu and change source to Uni-map or base map, wait a minute then change it back to auto and sometimes it will load sometimes it take 10-15 minutes to load.Quote:

That plastic bracket is just the part that came with transducer that goes into the metal transom bracket. You should already have that. Unless they didn’t give it to you. I have never seen a bracket like yours on a transducer before. Here is picture of complete ashy. The part that goes to transducer is on right. It doesn’t fit perfect on motor housing but mine hasn’t moved yet. But before purchasing something I’d sure try some rubber to isolate it to see if that helps.

Thanks cray they put the box in a storage compartment on the boat and I bet it’s in there I never opened it just took to the folks that installed it. I’ve got a roll of thin rubber stripping that I think will fix the problem. Thanks for all the help

RF interference can encroach into sonar units by 2 paths - xducer/xducer cable and/or Sonar power circuit ...
One should determine which of these 2 paths that the interference is encroaching ...
This is best determined by removing the xducer and its cable completely from the trolling motor and from under the deck (where a lot of power wires reside) ...
Test the xducer in the water far away from the trolling motor while keeping all of the xducer cable away from anything 12v that is not the sonar unit 12v itself ...
*If the interference is still present - it is encroaching into the Sonar unit power circuit - and no amount of xducer remedies will help ... track down where the trolling motor power and Sonar power are allowing interference encroachment ...
*If the interference goes away - it is indeed encroaching either into the xducer housing (possible rubber cable strain relief damage) or encroaching into the xducer cable (possible nick in the cable somewhere).. or xducer cable too close to trolling motor power wires ...
If the interference is indeed encroaching into the xducer or xducer cable start by testing the xducer housing close to the trolling motor housing ...
*If the interference is still present - it is encroaching into the xducer housing ...
*If the interference is not present - it is encroaching into the cable somewhere ...
