Tranducer folding up due to high speed

[bluewingjb]

My transducer on the back of my rig has been folding up so to speak, due to high speed. I tightened the bolts but it is still folding up. Anybody have a similar issue and if so how did you fix it short of removing the transducer. I dont want to have it shoot through the hull due to the loss of signal. I was thinking of adding a support leg on the top of the transducer that hits the bottom of the hull, the transducer is mounted at an offset so there is flat hull above it. The leg would prevent the transducer from folding up. Just looking for any ideas.

U can always add a gussett to support, remember if too secure and you hit a log or object, it will be subject to damage. May want to look at location mounted, probably the water pressure applied when comimg onto plane is the problem, not the spped alone...if is speed , u have it mounted too low in water at rear transom!!!!!!!!! emoGeezer emoUSA

A pair of star shaped washers between the transducer and the mounting bracket may add enough tension to prevent the transducer from kicking up at high speeds.

I'm seeing more amd more transducers mounted on the jack plate

 

[bluewingjb]

I havent seen one on a plate yet. I think I found a solution. Will let you all know

 

[Tangled]

i have a 98 hrydro sport and im about to mount a side image and im wondering if it would be ok to mount it on the jack plate,without it being a problem

 

[AreTheyBiting]

I looked into that for my side imaging and decided against it

I have seen several mounted there but I ended up mounting it to the transom directly under the jack plate

let me see if I can attach a pic

this was taken before the cables were run but after the transducer was mounted

Raise the transducer it's too low if it's popping the transducer up. It should be an 1/8 to 1/4 inch below bottom of hull normally to get clean readings.


TRANSDUCER Moutings:

Transom: If you want both on and off plane speed readings you MUST mount the external transducer to be below the hull of the boat about 1/8 to 1/4 below pad. It has to be in clean un-aerated or turbulated water to get readings at speed.

ShootThru: For Fiberglass boats a Shoot Thru Transducer can be expoxied to shoot thru the fiberglass hull and provide all speed readings. With todays modern sonar and proper installation very little if any signal lose will be seen. I recommend pretesting before installation to find best hull location

SIDE IMAGING Transducers: Many are opting to mount high for OFF-Plane readings only and to Protect these more expensive transducers by mounting higher on transom or Jackplate. Mounting higher than bottom of Pad will not allow 2D Readings from these transducer to read at speed. A second transducer and Y cable will need to be installed if you choose this method.

My ducer doesnt have speed. I fixed the problem with a 90 degree 2 1/2 inch bracket. I just mounted it on the area of hull that extends over the top of the transducer and the 2 1/2 leg that points down works perfectly as a leg preventing the ducer from folding up. All is good now.

You lost your breakaway protection then.

The Speed is Boat speed not a Speed Sensor on transducer I'm talking about. I would cation taking break away protection away. Can you post images of your transducer on the boat.

I had this problem with my Hummingbird sidefinder sensor. I put a cable tie around it so support it at high speed and
still give me a little bit of protection since the plastic tie will snap if it's hit hard.

 

[Benny]

all you have to do is read the book

 

[bluewingjb]

Benny I did read the book and worked on several options before going with what I ended up using. Yes if I hit something the ducer will not be able to fold up out of the way but with where I have it located if I hit something that would fold it up I have bigger problems. So far its working great... I will post pics tomorrow of what I have done. After some thought I might modify the support to allow it to bend up under harder pressure than just the boat speed. That way I would still have some sort of protection.

To obtain an optimum sounding, any transducer must be in direct unobstructed contact with the water. An imaging transducer, however; is best and most effective when used at slow speeds since its design is for precise, methodical imaging, thus there is no need to drag it around at speed like it was a high speed transducer. An imaging transducer is best mounted above the running surface and below your loaded at-rest waterline.
