Side Image beam hitting motor

Just got a Garmin 93sv echomap plus and tried it out yesterday for the first time. The left beam appears to be hitting my motor. My boat is not big and has a 9.9 on it. Not a whole lot of options as far as where to mount the transducer. I had to completely lift the motor out of the water to get it to be clear of it. Anyone have experience being able to correct thois? I'm wondering if i'm going to have to just live with this. Since I had to left the motor completely out of the water could it be that the transducer angled up when sitting in the water?

check the water line on the side of your boat and make sure the 'ducer is in line with it. You might have to live with it OR you can put a manual lift to get the motor farther away from the back of the boat. :twocents

wannabe is correct that aligning your xducer with the water line on your boat is a good way to make sure the xducer is parallel with the water's surface ...

Outboard lower unit blockage is a common challenge with SI xducers on a transom with no jack plate to move the motor back out the SI beam ..

Tilting the motor up usually eliminates SI blockage ...

Do do you have anything mounted to the opposing side of the transom ..(ladder, speed sensor, another xducer, live well screen) ...??

I didn't when I was testing but my trolling motor is transom mount.

Can you post a side imaging Pic showing the issue you describe ...??

You can install a second SI transducer on the opposite side, buy a Y cable to split the signal and have a clean shot both ways.

I have a transom mount trolling motor on that side which might create another problem.

Here are some photos. The one that shows good structure around a dock is deeper water. The other two are one with motor down and one with motor up. Attachment 333016Attachment 333017Attachment 333018

Can you post a pic of the transom area?Would it be possible for you to mount the transducer on the transom mount trolling motor?

The trolling motor comes on and off. Not going to be possible plus I need to run it when trolling motor is not down. This is a 1973 Mon ark. Nothing fancy. Someone suggested I take the hyrdrofoil off since it's just a 9.9 motor so I did that yesterday. It was on there when I bought the motor. Attachment 333020

Why is your side image range so short in the first 2 pictures? Usually the range of 3 times the water depth is a good rule of thumb but I keep mine in the 60 to 70 foot range.

I'm not sure if I moved it or it moved in it's own.

Unfortunately only HB has that option ... OP states he has Garmin ...

Rickie

Seems your option is to tilt the motor as high as possible ...

Or ... Don't worry above the echo showing at 2ft from the xducer ...

I would highly doubt there would be any fish 2ft from your xducer that the echo is covering up ...

How long is the transducer?
I know people don't like to drill holes into their boat but is it possible to remove the transducer from its current location(appears from your picture that the current mount adds an addition 1" or 2 to the length of the transducer) and hold it by hand directly in front of the motor against the boat and have someone turn the motor to see if the motor interferes with the transducer?
I have a Lss1 transducer mounted in this area( on my boat with no interference with the motor in any way(25hp suzuki).
You could also temporarily mount the transducer to a 1x4 piece of wood and use a "C" clamp to hold the board to the transom and try different areas to see if you can find a spot with no interference.
With the hydrofoil removed and mounting the transducer against the boat maybe this would solve your issue.

I would caution against mounting any transom xducer "too" centered in front of the lower unit ...

The xducer housing itself will create aerated water, that can possibly get into the lower unit water intakes and cause motor overheating issues ...

The transducer is 6 1/2 inches. The mount adds an extra inch. I just had the mount put on to avoid hitting the bolt you can see at the top of the mount.

I just got off the lake and used my Echomap Plus 73sv for the first time. I have my transducer mounted on the port side, with a trolling motor on the starboard. Between the two is a 30 hp Evinrude, powering a 16 Lund. I normally run the motor in the first tilt slot, rather than all the way down. Being concerned about having tha same problem you experienced, I was hoping my normal running mode would be okay. It was, no darkened area, full view. To say I am amazed with the Garmin is an understatement. I am so glad I went out of my comfort zone and bought the Garmin. Try tilting you motor to that first knotch, see or you boat runs okay, and hopefully your SV will be corrected like mine was.
