Yes, I have two thru-hulls there - one for the speed wheel and the other for 
the depth. Plus the hubs for the mast wiring (one for the Nexus system and the 
other for the lights). The speed is pretty far forward and as close to the 
centerline as possible and the depth is back a ways and a little outboard so it 
doesn't get into the prop wash from the speed.

My head drain is in the head cabinet (actually three, the drain, the sink 
input, and the sink output). It is pretty busy in there.

    Curtis, your 30 is not cored - at least below the water line. I've mounted 
a transducer in mine - under the dinette seat - all solid glass.

      I was thinking that I would need to separate them so as not to interfere 
with each other? I was thinking my C&C30 MK1 was a solid Glass bottom "Not 
Cored)?  if the new transducers can see 300 feet deep can it not see forward 
the 25' of separation from one end to the other of the boat? 


      Thanks

        If you have transducers working on the same frequency you will get 
crosstalk. If you have one instrument @ 50 Hz and one @ 200 Hz there should be 
no problem. 

        You can get around this by mounting the transducers very far apart, but 
apart from showing you what you just hit I don't see much point in having one 
at the stern. 

        In-hull transducers generally lose a lot of depth because the signal is 
attenuated by the hull, the thicker the hull the smaller the signal. They don't 
work at all with a cored hull unless you remove the core in that area and 
replace it with solid glass. If you can put up with limited depth, the in-hull 
installation will be easier and probably won't leak. : )

          I have a new Garmin ECho 50s  
          I would love to know how to set  the wind gauge up to the ST50 Gauge 
and the Garmin at the same time. I know it can be done . I want to keep 2 
different depth sounders one in the New Garmin transducer and one in the older 
st50. One question on that topic? should I put the 2 depth transducers one 
astern and one forward? so I can see both ends of the boat better or keep them 
both just forward of the keel. and sense I have not purchased the Garmin 
transducer yet do I get the in-hull or the threw-hull?

            Hi Michael,

            Please post the Seatalk talk info. 

            I don't need it right now but I save these kinds of posts for when 
I do need it. 

                    Cheers, Russ

getting the

              interested.
