Default Just bought the Airmar tilted element transducer...

Now for the install.... and after reading the thread about patching the hole after installing one of these in the wrong place, I wanted to make sure I get it in the right place the first time (it's a 2 3/8" hole). Boat is a 20' Hydra-Sports Vector, and I plan to install 18" to 24" from the transom, approximately 8" to 10" out from the keel on the starboard side. This is where indicated in the installation instructions. This will obviously be in front of the prop, and it will also be in front of a livewell pickup. Now given this thing only hangs down about 1/8" from the hull, will it generate much in the way of bubbles, and potentially cause cavatation issues, or a problem with the livewell pickup? I just can't imagine it would cause much turbulence. Anybody done one of these, and where did you put it? Thanks!

Shouldn't be a problem at all. The livewell pickup doesn't care if there are a few bubbles going in it. Sound's like your on the right track.

In my experience with small, planing boats, the best location is usually as close as you can get it to the keel and the stern - 10" off the keel and 24" forward will probably not work when you at WOT because the transducer will not be in "clean" water.

To find the best position, I would suggest you experiment first by placing the transducer inside a bag of water and then placing it inside the hull in your candidate position(s) (you may need some small sand bags to hold it in position). Then go for a drive and see if you have bottom lock at WOT. Keep trying until you find the best position.

I have attached below the recommendations from Airmar.

Good luck,
Killeen

Question
Where is the best place to install a thru-hull transducer on my planing hull power boat?


Answer
Mount the transducer well aft, near the centerline, and well inboard of the first set of lifting strakes to insure that it will be in contact with the water at high speeds. Mount the transducer on the side of the hull where the propeller is moving downward.

---Outboard and I/O - Mount just forward and to the side of the engine(s).

---Inboard- Mount well ahead of the propeller(s) and shaft(s).

---Step-hull- Mount just ahead of the first step.

---Boat capable of speed above 25MPH (25kn)- Review the transducer location and operating results of similar boats before proceeding.

Call HydraSport. They will tell you the best place to mount it.

Yes, Gem Electronics is the only place you can get one. Airmar's website needs some upgrading. The imfo is very small there.
You will find more here, as there was a long thread and I posted pix's too.

tpp517 Did you get my email?

It's been installed, but there is a lot more work being done to the boat, so it will be a little while till I get to test it.

Tilted Element Transducer - As stated not much for details on Airmar's site.

Couple questions for whoever knows?

Is this a dual frequency 50/200 unit? If not - what is it?

600 Watt Unit?

Does it have a Raymarine Part number yet - or can you only get it from GEM and have them put the connectors on? Interested in using it with either a Raymarine C or E series unit.

What did it cost?

I'll probally end up calling GEM but curiosity has the best of me at 11PM...

Thanks,
Steve

Yes it's 50/200hz

600 Watt Unit?
Yes

No, only available thru Gem. When you call them you tell them what you want to hook it to. They will provide a cable to do that.

What did it cost?
$208

I'll probally end up calling GEM but curiosity has the best of me at 11PM...

Thanks,
Steve



Look at the link I posted above for more imfo.

All is well that ends well. My buddy tried his boat after the installer moved the location of the transducer. The installer decided to leave the mis-mounted one in the hole. So now he has two in one boat. Anyway he sea-trialed his boat today and the ducer performed flawlessly. So no hole to patch after all.

They are onlt available in 600 watt's as far as I know. Again there is not a lot of imfo. Call Gem.

The tilted-element transducers are rated at 600watts rms (2% duty cycle). And I doubt that you will ever see a 1kw rms rated tilted-element transducer. The reason is that the fitting limits the size of the ceramic inside the transducer. If you cut the duty cycle to 1% you could (in theory) put 1.2kw rms into that transdcuer however that much power into that small ceramic would probably cause cavitate. E. Fitzerald.
