| Rigged up my 2011 esox mag with a humminbird 998 side imaging. Been having problems with the side imaging reading to the "left" side. It will only read maybe 30 feet to the left. I believe that the 2 livewell intakes may be in the way. (see photo) Today I added a 1 inch thick piece of plastic to move the transducer out away from the transom. This didn't help and it may have made it worse. Any one else have something like this happen? Not sure what I'm going to try next. Hate to drill any more holes in the boat.
thanks
Brian

Location: Grand Rapids MN | I would guess your other transducer is still in the way since it is lower than the HB transducer. From what I've read on HB SI people usually mount the SI unit as close to the center of the boat hull and as low as possible. But this usually affects the 2D sonar quality so they will add a secondary transducer for the 2D but move it further out to the side and higher up or it will be in the way. With out drilling more holes I would say try swapping locations of your two transducer. This might allow you to see the full range. Usually something partially in the way will only 'cloud' the image and not entirely block it but its hard to say for sure.
Good luck with it.

Location: Kodiak, AK | Where's your motor at when it's tilted down? It looks free and clear tilted up, but may be in the way tilted down. You may be hitting the mid section of your motor and if shimming it aft made it worse, that would make sense. Tilt it up on the water and see what happens to your picture. Alot of guys with plates will hit them or get resonnance from them if their plate is down or ducer is mounted too close.
If not, then yeah, you've got alot of stuff hanging off the boat to the left of your SI ducer. You'll need to move it downward, or if that hull is stepped, put it on the step, which is where I have mine mounted.
Switching the ducer mounts is a good idea, just make sure it clears the motor when tilted down and trimmed all the way down, and while turning.
Edit- looking at your pic, your hull isn't stepped unless I'm seeing it wrong. So disregard the step idea if that's the case.

Location: Stevens Point, WI | I run a Lowrance and don't have an Esox Mag, but like the guys above said, I think you need to have it further to the right, at least between the two bunks. I wouldn't hesistate putting the ducer even further out. This transucer isn't the same as your 2D. In order for the Side Imaging to work, slow speeds are your friend so there is no reason it has to be at the very bottom of your hull. As Efly said, you also maybe getting feedback from the motor when it's tilted down being that close.

Location: Kodiak, AK | Really TJ? I'd move it further to the left and put it as close to the conventional ducer as possible. I have LSS as well, and like you said, it works differently than the 2D sonar, but I'd move the SI ducer down to mirror the 2D ducer on the righ side of the livewell pick ups. That'd put it below all "clutter" mounted on the transom and likewise it'd have a clear shot to the left, other than the motor. I'd think putting it further to the right would put the pick ups and 2D ducer in the sight path.
But I do agree entirely that there is no problem mounting it higher and that slow speeds are your friend. I've got mine on my step, so it's out of the water on plane, something you can't do with a 2D ducer. |

Location: Stevens Point, WI | Efly, I could be wrong, but if you saw where mine is located and how well it works, you'd probably be surprised. I personally would not want mine located where the 2D ducer is because of the motor and the potential issues you'll have being that close. I was told specifically do not mount on the transom in line with the motor.
I also think the Side Imaging ducer could be moved down a bit, at least flush with the bottom, hence why the spot between the two bunks is where I'd personally put it. |

Location: Grand Rapids MN | Just to clarify I hope I wasn't implying these are the same as the 2D. Mounting it lower means it will clear motor mounting brackets and the motor itself with less trim required. But people say when they place it lower, and therefore more center and closer to the motor, that they get to much turbulance from the motor and their 2D does not work as well; therefore generally they add a second ducer for 2D use only in a much more 'prefered' location.
I would caution spacing the tranducer to far out from the hull. Unfortunately those trandsducers have plastic mounting brackets that seem to have questionable strength. I've seen many complaints of transducers falling off without taking any direct hits.
I think Esox was onto it and I missed the obvious based on your pic. If your motor wasn't trimmed out some that it would completely block the signal. Usually partially blocked signals look whited out or cloudy. |

| Well from where it is i don't think your going to get 2d readings while on plane anyway. So if you move it lower to clear the stuff it will not make the 2d reading any worse in my mind and you will get 2d readings at a higher speed maybe not at full speed. If you don't need the 2d readings at high speed then keep it up. The reason people keep it up is so they don't break it off. I have the same boat and I use lowrance lss-1 transducer and the regular skimmer transducer and mounted both of them on the right side in between the two bunks i get "side scan" up to about 15mph. I will post a pick of my ducers if you want even though they are different brand.

| Thanks for all replys. Here is some more info. When I 1st set up this boat, I had a guy glass in a transducer to read when motoring at all speeds and then he mounted the SI ducer where its at. (He is on humminbird prostaff and has done a bunch of these) With this set up, (before I added the white plate) I got only about a 35 foot reading to the left. He came with me and said the livewell intakes were the problem and I needed to move the ducer out and inch or so. Also, thats when we had to add the high speed ducer to the back of the boat because I was loosing a reading at 25 mph. Thus I don't know if its now an issue or not. I'm tempted to get out some duct tape and play around with spots. Wish I had more time, Canada in about 10 days.
Thanks, and keep suggestions coming |

Location: Kodiak, AK | Well a simple test would be to trim your motor down all the way and see if the motor's mid section gets in the way of the ducer's side shot. If it's totally free and clear, then I'd mess with the pick ups.
Here's mine, as far as it's proximity to the motor and it works well.

Location: Rhinelander, Wisconsin | The mag has a pad, but no built in set back.
Tuffy recommends the high speed transducer is placed between the bunks in the tunnel area of the sponsons on the starboard side close to the lift strake; that's where the cleanest water flow is at high speeds. The surface of the transducer should be dead even with the running bottom with the rear of the 'ducer tipped down about 3 degrees. As mentioned, the side imaging unit doesn't need to be placed the same, as it's used at slow speeds. The difference between the two pictured mounts as far as a clear shot past the front of the lower unit is the built in set back on the second; it provides a bit of extra space between the side scan 'ducer and the front of the lower unit and it appears the transom angle is a bit sharper on the Ranger in the mount area. The 1890 and 2060 have built in set backs, the 1700 has a true V hull, and the 1760 has a semi-high performance running bottom. The Mag is a sponsoned V, and has a pad created when the original Marauder hull was split and widened to make the Magnum 80" wide from the original 70" design. |

| Just tried a couple of things. 1st I left things as it was in the pic but lowered the ducer as low as it would go mounted there. I did trim motor way up and still no difference. I then duct taped the ducer more to the right (between the bunks). This did give me a littler more of a left side reading. Also when I trimmed motor up, the section that was reading properly to the left did become "lighter" in color or in other words, a better reading. Will try moving it around more with duct tape. Today is my last day to make an adjustment. HOpe I can find the right spot.
