The transducer could have a problem with the right side Si sonar.
The installation of the transducer could be the problem.
The unit could have a problem with the right side Si sonar.
Your boat may list to one side while in use on the water.
Let’s try and eliminate some of these:
- If you know of anyone else that uses a Humminbird Si model unit, test their unit on your transducer and power cable (even if you have to hold the cables in by hand). Any Humminbird Si model will work for this test. Cross-test your unit on their boat and transducer as well.
- Take a few pictures of the installation of your HDSi transducer and post them back here. Take these from transducer height. We need at least one pic of the overall transom of your boat and at least one looking from the left side of your boat across to the right side of the transom. One from directly behind the transducer will be helpful as well.
- If you are using an AS-Si-DB-Y or transducer switch; take these out and direct connect the HDSi transducer to your 898c HD Si unit and see if it makes a difference or not.
- If your boat is listing badly enough to cause this, you need to think about rearranging the load that your boat is carrying.
