We got depth! We have our Airmar P79 transducer working

October - Paradise Village Marina in Puerto Vallarta Mexico 
 

 Yes the transducer is now working! When installing the transducer we had sanded the hull smooth and in doing that the hull in that spot became a little concave.
We also bedded the transducer with silicone and this raised the housing a bit. We then put in the recommended amount of 95% (or so) antifreeze and it never worked. We did see the transducer on the Garmin network though. So before un-snaking the 20’ cable from the bilge and then doing the water test, we decide to try more fluid.
I, of course, did not measure - I just poured in antifreeze until it overflowed and put the top back on. The transducer then worked! So it was a fluid problem, not enough fluid. We then had to sop up some fluid with a paper towel to get the level down some and re-secured the top.
The tide is going out.
 We have a 20’ Garmin backbone cable attached to the 20’ (I think it is 20’) cable that is attached to the transducer and this is not causing any problems.

 This is the first time we have had depth in 10 years! We had a Catalina 30' for five years without a working depth gauge. And we have had this boat for five years and have sailed from San Diego along the Mexican coats as far down as Melaque\Barra-Bahia de Navidad and then back here to Paradise Village Marina in Puerto Vallarta Mexico with a depth gauge but it will be much nicer to have one now.

  1. I'm sure you have thought about this, but I'll toss my two cents worth in anyway.

    Remember to set the offset for about 5 1/2 to 6 feet below the water line, depending on how the boat rides in the water.
