Thread: NEED HELP - Lines in one side of Sidevu

It needs to be dropped down so the mount for the motor doesn't interfere. Other than drilling more holes is there a reason you don't want to move it down to the step?

I don’t think it’s the placement of the sonar.

So this is a screenshot of mine back in Sept 2023. It is mounted on the starboard side of transom like yours. It is mounted like manual says with bottom of transducer flush with the bottom of the boat.
1) The blue arrow is my main engine, not running and only shows about 2-3 feet from the transducer (which it is). But it is only that line. Your picture shows 10 feet interference which I’ve never had.
2) the first pic isn’t the best screenshot to show this but the if I do not trim the engine up a bit, the port side of my sidevu is largely useless.

This is what it looks like with engine trimmed down.

This is why I don’t think it’s a mounting issue but I could be wrong. I can’t remember where I read this but is anything else hooked to your battery other than the chartplotter? Even a dual battery charger?

the holes I wouldn’t mind if I knew it would fix it. However the bigger issue to me is there’s not a flat place on the step to mount it to. It needs to go between where it is now and the fittings on the bottom of the hull. That entire area is just a gradual curve to the very bottom of the hull

I had a 4 bank minn kota charger connected to the battery but pulled that off because I was getting trolling motor interference with it. So no just my electronics are on the battery now. It has to be something on the transom causing it. It worked fine pulling the transducer and putting it back on the kayak, with both the ultra 2 and Echomap 73. It works moving the transducer to the side of the boat, and works moving it lower from where it is.

I asked Garmin about adding another transducer twice. The first said it wouldn’t work, that you would need to use two different transducers with only side imaging. The other said it would likely cause more interference and problems. I’ve about decided that they don’t really know much because I’ve received all kinds of different advice on the issue and it’s all over the place

It's you're positive it's "something on the transom" then start by removing that metal strainer and trying it.

already did that to test for the next trip. It has to be someone on the back, I’m just not sure what it is or what the cause is.

I have seen scenarios of multiple interference lines on one side of the center line ...

Most often it was determined that the SI beam was bouncing around inside the vertical supports of a Jack plate ... your motor mount is similar to a Jack plate ... their fix was adding a plate on the bottom of the Jack plate and mounting their transducer to the Jack plate cover ...

You don’t have a Jack plate that a bottom plate could be used ... nor the clearance for the transducer there ...

You indicate that the lines go away when mounted to a pole and putting the transducer deeper into the water ...

This may be the goal ...

I have seen scenarios where one could fold the transducer bracket less than 90° and attach the top half of the bracket to the underside of the step (horizontal) instead of down on the vertical surface of the step ...

If this is a possible mounting idea, I would suggest in the center of the keel and aft far enough to clear all the ports on your step (but still clear the big motor lower unit with it trimmed in as far as possible) ...

would you see any possible negatives of extending a piece of starboard down off the transom like this to extend it below toward the step?


here it is below the engine bracket in the step. I think that’s what you mean? That would be a good location but I’d just hate to drill holes there and it still not work.
