Im fitting a raymarine depth sensor and was thinking of using the old housing that's glass the the boat on the raymarine web site there suggesting epoxying the sensor to the hull.
I was thinking of filling the void with glycol and mount the sensor into the original existing mounting ?

That should work ok ?

I just stuck mine to the hull with some silicon sealer. Works fine.

thanks cisco
You back in the water yet . I should be back in in the next couple of weeks.

My transducer is identical to Ciscos. I used 5 minute Araldite. Works perfectly. No air pockets is key to success I suspect.

Id like to have the sensor@ 90 degrees to the water line which the housing would give me rather than try and glue to the hull side Ill work it out
Thanks

Hi HG

When you remove the original one what is it immersed in

Perhaps the instructions say to epoxy it to the hull because it is a simple way to fit it

It seems to me that if you have the original spot available and it will work it is shame not to use it

Raymarine do something that is similar to your original housing www.raymarine.com.au/view/index-id=1479.html

I've sent a email to Raymarine asking that Donk
I've read on google that few year's back some one did that I think the liquid they used was glycol
The original housing is the correct angle so I'd like to use it

Hi HG

Castor oil has been mentioned a bit on the web as well

Regards Don

Here is som info from Airmar who probably make the Raymarine transducer www.airmar.com/uploads/InstallGuide/17-217-01.pdf

With the depths your looking at it's not that critical. Best is centreline forward of the keel, halfway between the bow and the front of the keel angled slightly forward. At the speed and depth you will need the sounder it is only a slight angle forward. There may be the odd bubble in resin or silastic but your shooting through a 'glass hull anyway which may have a slight void or defect.

Mine is in castor oil. Works perfectly.

word has it that's its good for blockages as well Muzz65 it's on my list

Years ago I bought a boat that just had a pvc tube filled with salt water all good.
Now I have another boat with a rectangular icecream container - bottom cutout to the hupll shape for vertical sitting of the now rectangular transducer. All good filled again with salt water.

If you do choose to mount it elsewhere you can use Blu Tack in a big ball press the 2 together like with the silicone etc and test the spot b4 you glue it permanently or be lazy like me and just leave it in the Blu Tack because it works.

has anyone tryed this method in a timber boat?

Hey S.A.
I've ready where a guy used one with a 3/8 ply wood hull
He wrapped the sensor in cling wrap and epoxied it to the inside of the hull
When the epoxy had dried he removed the sensor UN wrapped the cling wrap off and then siliconed the sensor to the epoxy giving him a straight beam through the hull

I'm interested in any personal experiences with this method on steel hulls too, particularly with the Raymarine transducers. Most of the advice from manufacturers and online seem to say the in hull mount will not work with steel but currently have an old Seafarer unit with an in hull transducer that seems to work ok.
