Transducer Location Pic – Opinion?

I mounted the HB Si transducer and ran it around last night.As you look at the pics, it doesn’t look to be in the best spot to me…what do you think?
Couple issues:

1. Lots of spray — rooster tail 4 feet high and spray against the side of the motor – I have the black rubber plug placed in the transducer gap.

2. I have the transducer mounted on the port – Left SI is awesome! The right side was not…could only see half as much and it was fuzzy in nature. I’ll try to capture an image soon and post.

More scouting than fishing, but unit already showed me spots I should have been fishing…right under my nose! I can’t wait to get the Lakemaster chip and see what that does.

Thanks for any ideas on my transducer location!

I beleive you have the same problem as me, your lower unit is blocking the ducer from shooting right, when scaning at idle spped lift your motar up and theright side should be perfect, as for how to fix the problem, Im lost if I move it down any more my lower unit will crush it when trimmed all the way down

I have a hunch that if you tilt the transducer down one click, that will help. I’m going to test that next time out. Of course, I’m running two transducers. So I’m not worried about high speed performance of the SI transducer. Just an FYI.

The lower unit does get in the way of the SI as well. I don’t notice it as much on this boat, but it was very noticeable on the old rig.

Do you think that I need to raise the transducer at all? It is working where it’s at and the Switchfire sonar worked just fine at cruising speeds as well.
I am concerned that it’s hanging down there too much.

You might benifit from getting the second highspeed ducer, from my understanding it is around $75. That way you can raise the si ducer up a bit. It will get the expensive SI out of high speed water that could have debris and should eliminate the roster tail.
As for the fuzzy right side? trim motor up, maybe one click down too and give it a shot is all I can offer. -Mark

Since you have the plate attached to the boat (and won’t have to drill more holes in the boat), try moving the transducer closer to the centerline of the boat away from the chine drop it down a click and give it a couple of degrees tail down attitude.
it aint’t a science….its an art and if it don’t look good just paint over it.

I bet you are hitting the motor lower unit with the right side imaging. Trim up the motor and see if the image improves, I bet it will.

Hi,

From the looks of your transducer, you installed a “7” series SI Humminbird. Did you get/install an anti-spray plug at the base of your transducer? It’s a small rubber plug that comes w/ new Humminbird “7” series units (in the box or can be requested from “H”) – this helps w/ the spray problem coming off the xducer.

The problem w/ the right side SI “wing” not working well is caused by some obstruction along the back of the boat block the SI signal. This could be the main motor (can you trim up? – it only takes a few degrees) or something else. If the blocking object cannot be moved you may want to consider going to a SI splitter install, where you have two SI transducers mounted (one on each side of the boat connected together w/ a special cable (AS-SL-LR-Y)).

Take care,
Roger

Here’s a wider view of the transom prior to mounting the HB transducer. I remember reading about guys having issues with the screens on livewells. I suppose that could be my issue too. Easy to check by taking it off. I suspect it’s the dangle of the motor…tilting it up a bit will just have to be the way it is, I guess.

I can see I’ll have to try moving it down and right on the mounting plate. Hopefully, that hull strake won’t affect.

OR

I’ll try moving the whole transducer a little bit vertically so it doesn’t hang below the boat.

All this thought on a transducer…solving world hunger might be easier! And that will be accomplished by catching MORE fish due to the HB!

Hi,
Looking at your lattest picture you may want to be careful when moving the “H” SI xducer up on the transom mounting plate. If you go up far enough you will have issues w/ the “L” xducer mounted next to it on the left, and 2D readings from the “H” SI xducer will be bad at speed. Question: Are you using the “L” sonar box anymore? If no, get rid of the xducer (and wiring) and you will have more mounting options.

PS. On my boat I am running a 797c to a Quadbeam xducer (retired it as a SI unit) on one side of my boat, and a 998c to HDSI and 2D xducers (connected w/ a splitter cable) on the other side (of the boat). I also have the main motor (trimeable – you only need to do that when you using SI/DI screens), a 25HP kicker, and live well intake screen. The HDSI is mounted below the livewell screen but not below the boat hull (only using SI “wings” (not 2D)). All the other xducers are mounted at least 1″ horizontal above it (looking at the back of the boat). If I can get my install to work you should have no problem.

Roger –

Thanks for the replies. I think I will scrap the old lowrance transducer that is up and to the left. The only reason I have it still on there is backup in case the HB goes down. I suppose I could unscrew it and pull it back into the belly pan inside the boat–just in case. I’ve had electronics quit mid-trip and it can ruin things in a hurry.

Another question: do you put the third screw in to “lock” down the transducer?

Hi Scott,
I would guess one would only use the “lockdown” mounting option if your xducer is “kicking up” at speed – my boat is not fast enough to cause the xducer to do that (about 35MPH max.). I do use the third screw (under the flip bracket) to “fix” the position of the xducer bracket once I am happy w/ the install (level?/height?/etc).

PS: I see you posted a similar topic on <SideImagingsoft.com>. On that website if you look at the Image Gallery you will find neat stuff like Installation Photos, etc… Other resources is Yahoo Groups (sideimaging), Bass Boat Central <bbcboards.zeroforum.com/zeromain> (both Humminbird and Lowrance links), Unofficial Humminbird Forums <www.xumba.scholleco.com>, <crappie.com>. That’s all I can think of! Some of them have install photo links that you might find useful for your application.

Take care,
Roger

Life’s too short for all this nonsense. (sour grapes cuz I don’t have one)

It is too far below the boat. It will get smacked by something for sure. I have mine just above the bottom of the hull. I had to double up on the plates to have it miss all of the stuff near the bottom of the boat and it worked out great. I’ll take a pic of it tonight for ya.

For some reason the site isn’t letting me load .jpg photos today. I can email them to you if you wish.

Chances are they are to big. My camera causes my pics to be too big. Open them in paint and shrink them down.

+100. My thoughts exactly.
