Transducer Mounting

Postby DCRAIN » Sun Feb 01, 2009 11:04 am

Any problems I should be aware of in mounting a transducer on the transom, or am I better off using a thru the hull design?

I would guess most are mounted on our transoms. Just make sure its on the outboard side of the sponsoon.

I've narrowed my search of a chartplotter/sounder down to a Lowrance HDS 5 or last years Lowrance LCx27c. I don't have a lot of room to mount one of these on my 266LC. The question I have have is this; the HDS 5 comes with an internal antenna. Is this going to be a problem when I have my cansas top up? Am I better off having a external GPS antenna mounted in front of my windshield? I appreciate any thoughts or suggestions.

I emaile to George Poveromo about a week ago.
He uses a Lowrance HDS ,ie their new broadband depthfinder.
at the MIA boat show I talked to the Lowrance guys in the Marriot lobby.
They said going broadband allowed them to use a lesser wattage transducer and mount it on the transom.
read a mag article or Lowrance blog on the web about Poveromo usung Lowrance BB unit.
He is using an Airmar B260 that was molded in the MAKO 28' hull. He says the new BB unit works much better than any previous Lowrance.

Typically its ok thru canvas, But I'd go Garmin

Based upon the advice of others on this forum I abandoned my plan to install a thru-hull transducer and instead installed an Airmar M260 In Hull. This is a powerful transducer that is working perfectly with my Garmin GSD22 Digital Sonar. I get a solid bottom reading at 30 knots in 100' of water. The reasoning behind this choice was sound: a) it is challenging to locate clean water coming off a cat hull. b) no matter how you slice it, a thru-hull is another hole in the boat and I figured the less holes the better. Some advice after installing one of these:

1) ideally you need a flat spot in the bilge for installation. That said, the M260 is designed such that you can trim the enclosure to fit your hull profile if you don't have a flat spot big enough. Stay close to the rear of boat so it doesn't lift out of water.
2) pay close attention to the dimensions of the transducer.. it is far bigger than it looks in pictures and it is built like a tank! Picture something the size of a small car battery.
3) my cat has some sort of painted finish in the bilge. I originally sanded this using a heavy grit and then P-texed the tank to the hull.. it worked great for about 3 weeks and then I found a bilge full of antifreeze (you fill the tank with antifreeze). Use 3M 5200 Instead and be generous. I did this 4 months ago and it is working great.
4) The price of this transducer took my breath away but if you search around you can find it in the $700 or even $600 range.. it hurt when I laid down the credit card but I saved 10x that in installation headaches and now that I have it I realize it is one of the most important pieces of equipment on the boat and well worth it.

You can find info on this ducer at http://www.airmartechnology.com/airmar2 ... enData.asp

Good luck!

Trent - what model WC did you mount the M260 in?

I read some where that airmar has come out with a thru hull
ducer that has an internal tilting/self leveling element.
Sounds nice as this would help alleviate faring block and
free up some mounting location options.
I have never used an in hull ducer but my thought was that they needed
every bit of clean water that the thru hulls do.
Mounting location flexibility is always beneficial.

I looked over the airmar website of products and found nothing of a self adjusting or self leveling element on their transducers. They have a couple of models that can be manually adjusted to fit 2-22 degree deadrise.

ALL t'ducers need clean water, regardless of the hull type (cat or V) or ducer type (thru-hull, in-hull or transom mount). If you try mounting any t'ducer in turbulent or aerated water, you might as well turn it off until you slow to troll or idle speed.

My 1 KW M260 is hooked up to my Garmin GSD22 and it is awesome.

I found the article and apparently it is not a self leveling as I first thought
but can be purchased in different internal element angles depending on
degree of deadrise.
Still looks like a pretty nice unit.
