this is with TM in shallow water, the DI is in 8ft sitting still?

Is your transducer on the trolling motor?
If so, see if you can find someone else with a Humminbird Si model (any model will do) and cross-test your unit with theirs and see if the problem follows your unit or stays with your boat (transducer).
-
No it is at the back, Hydra Sport. I have been reading all day, I have a stepped haul which sound like that is bad. I looked and the jack plate may be close to being in the way? Like I said, the right side of the SI was great. I did make the speed the same on the finder. You can remove other post, not sure what happened. Thanks
-
Yes, it looks like the left Si sonar is reflecting off of the jackplate. You can try moving the HDSi transducer closer to the jackplate and I would lower it down as much as you can as well. Test this location at low speed only using some marine grade double-sided tape (available at many car automotive stores).
-
would that also cause the DI trouble? It says to keep it 15" away from the prop? I will lower it and get back out.
Does the remote have to be on to use the track to way points? I could not get the motor to go to the way points? Thanks
-
The Di sonar on the 998 units comes from the left and right Si sonar – so any problems with either the left or right Si sonar could show up on the Di sonar as well.
No, according to the I-Pilot Link manual you can travel to a waypoint by using the remote or the unit itself.
Do you have the i-pilot Link connected to your 998?
Are you running the most recent software updates in all three (998 unit, i-Pilot Link and Remote)?
-
I do have it connected, not sure on updates as they are all new. Trolling motor is last years and 998 is this years. The remote came with the tm.
-
Sounds like you will need to update the software in all three but make sure that you do so in the correct order when you do. The Humminbird web site spells all of this out in the download instructions for the i-Pilot Link updates.

I lowered the transducer to as low as I could put the mount. Still has the interference, the down scan was better, but still had it. SI seemed to just more it towards the bottom of the water column. Not sure what to do next? How level does it have to, if the boat picthes due to guy standing on one side or another would that do it? Pay this kind of money and I guess I have to keep the shore to my right?
-
I see it was tipped down, but the right side worked great again? Would whatever that is the the left of the transducer have anything to do with it?
-
The boat being unlevel will not cause this. It is some type of sonar reflection or a problem with the Si transducer itself that is causing this. Usually it is something to the left of the Si transducer that is causing this. A way to check this is to take the HDSi transducer out of the mount and temporarily install it on a pole that you can lower down into the water deeper than the boat hull and motor and see if the lines to the left side are still there or not when you rotate the transducer to point in different directions.
What is there to the left of the transducer? I see something in your pictures but cannot tell what it is or how far it projects outwards from the hull. The jackplate could also be causing this.
Make sure and tighten down the bolts that hold the transducer to the black plastic pivot arm. I hope that you used the locking start washers in there or it will continue to drop like this.
-
I will try the mounting on a pole next. We just got snow here so it will be a few days before I can get back out. The transducer is way lower than anything else on the boat now. I got the remote to record a track and go back on it. That was cool for the first time using it. I think the little black thing is the temp gauge for the front of the boat? It is only half an inch wide. Any reason it would be coming from the battery? Thanks
-
I don’t know about the temp gauge – it doesn’t look like the one Humminbird sells, so I don’t know why it would be connected to the battery. How far out from the hull does it stick?
-
1/2" I have the transducer mounted on a snow shovel handle and hope to go out this weekend and try it.
-
Here is the pics from today with the transducer on a shovel handle about 2 feet below the boat. I shut everything off, even ran a new lead to the finder. I spoke to humminbird today and they will not even have the new transducers in until the 25th. Guess I will have to use it like it is for the turnny on the 26th. What else can I do to try to fix this?
-
I went to Don's Marina in Lodi this morning and the guy was great. He put my boat in the test tank and try the unit with a different one. It still had the interference. Guess I need a new transducer. That sucks.
-
I found the transducer all over online? I wounder if I buy one, will humminbird still give me money back on the one that is broke? Anybody done this?
-
They may trade out a defective TD that was purchased from them.... but it would be a rare business that sales direct that would replace an outside purchase.
