transducer location

Hi
I’m having problems with my transducer and I believe it is mounted in a wrong place. I loose sonar reading at 7-8 mph and side image works only on starboard. Looking at the picture can anyone make suggestions where to move it? Thanks

I think your trailer gets in the way.

From the picture it looks to me like it needs to be placed on the back end of the hull and not on the transom. It should be placed on the same section as your drain plug.

It’s hard to tell from the picture, but if I remember correctly, the transducer itself should be mounted about 1/4″ below the hull line.

It appears as though your transducer may actually be slightly above the line of the hull. This can cause a low pressure area where air bubbles will collect which will eliminate the sonar signal.

I don’t see a problem with the location of the transducer on the transom other than the possible issue mentioned above. My boat and tons of other boats that I’ve seen have the transducer mounted in that same general area of the transom with no issues at all. My lowrance reads the bottom cleanly while running 45 mph.

I don’t know Dale, it doesn’t look like there’s enough room on that section of the hull.

Hi,
On a stepped hull transom like the Skeeter your probably going to have to go to a split xducer setup – 2D thru hull (highspeed 2D work) connected to the HDSI xducer (SI/DI work). HB makes a special cable (AS SIDB Y) for this.

Good luck,

People have tried to subtly say its mounted wrong… A SI ducer can be high like you have it. But a 2D needs to be into the water at all speeds to read bottom.

It is mounted in the wrong place. Think of how the water flows along your hull. At fast speeds your transducer is out of the water. At slow speeds it is in the water.

I’m not really liking my thru-hull transducer. If I had it to do over again, I’d put a high-speed transducer on the lower step of the hull with a Y-cable splitter.

Your transducer is in the wrong place for high speed running.

Like Wade, I wasn’t overly impressed with my high speed returns, esp. in deeper water / soft bottoms with my thru-hull ‘ducer. I added a transom mounted 2D ‘ducer on my 1850, and have noticed a significant increase in high speed reading capabilities. As stated before, it needs to be mounted on the “lower” step area of the hull.

I have had the lower one pop up when I run a bit to hard in rough water, and have switched back to the thru-hull. Nice to have both when that happens or if the external got knocked off by something (luckily, that hasn’t happened yet) good luck.

Do any of you have pictures of the transducer mounts?

I am wondering the same thing about the transducer placement. Maybe someone from SBC could help out and post somthing.

I thought so too……I have asked a couple questions about my new-to-me skeeter boat, I don’t believe they have chimed in.

Took quite a bit of tweaking and engineering, but heres mine..

Here is the best picture I could come up with.

This would be the set up for both the 2d and si on the transom

I take it this set uses the switch to change from SI to 2d correct? The 2d on the step part of transom and the SI under the motor. What if you dont want to use the swithc and just the DI ducer for everything?

No switch needed just the y-cable. If you want to just use the di I would place it where the 2-d is showing

Eric,
Is that picture from a MX hull?

yes it is

How does the y cable work? This is all new to me. How do you switch from 2d to DI?

It’s basically a splitter cable, you plug the 2D and SI ducer lines to the Y end and the other single end goes to the screen. The head unit reads the 2d ducer info for high speed and the SI ducer info for slow speed as if they were the same transducer, the unit reads both at the same time, so there’s no need to switch…The cable is like $30

Looks like in need to go find one. Are they all the same or different ones for different models? I have looks but not finding one for my 859 HD DI model.

Thank you for the information

There is only 1 y cable for all units EXCEPT the onix. All other units will use the as-sidb-y cable mgf #720055-1
