O.k myself and Steve (67hat34c) both have 34C's and have or transducer a little back from the forward bulkhead. Both of us get a lot of air bubbles when going fast. Mine was beautiful until my repower so the boat is out of the water more.
So we have to move them back some so I am looking for ( How far back do I go)? I am thinking about the area near the Transmissions. Anyone with a 34 or 36 that cruise at 20 kts or above have any suggestions from where theirs are placed.

Re: Transducer Location
Mine shoots through the hull of our 1977 36C. It is mounted in a "wet box" about 5 feet from the stern, and about 6 inches off the centerline. Works fine at 24 KNT cruise. You might try that first. Just dam up a 6" diameter wet spot about 1" high with sealing putty from an electrical supply place and pour in enough water to keep it wet. If you like the way it works, you can glass in something more permanent. Try moving it around a few inches/feet if it doesn't work right at first. I have heard that sticking the transducer to the inside of the hull with silicone also works, but havn't done so myself, so can't say for sure. Regards, Bob K

Re: Transducer Location
Do you have a proper fairing block on that transducer? Before I put a new hole in the hull I would try to make it work where it is. I really can't picture one of these lead sleds getting that far out of the water. Look at www.airmar.com they probably made your 'ducer and may have a fairing block for it. When you say forward bulkhead do you mean the engine room bulkhead? My transducers are just ahead of the engines and I have no problems, but so far my best speed has been 19 kts so this may not be relevant.

And yes I did mean the foward engine room bulkhead.
Thanks for the link will look into that site.Dan

Re: Transducer Location
Dan,
I have bronze through hull ducer in a fairing block located between the keel and the shaft about a foot or so aft or the trans coupling to the shaft in our 37. The ducer is connected to a Furuno 600 color LCD fishfinder. At cruise (16-19 kts) I get a pretty good picture, probably some turbulence as the picture is not as good as it is at slow speeds.
Almost done with the HI winter project on on the the fun stuff.

Re: Transducer Location
need some posted photos of installation and fairing blocks. I was wondering if you could fair it in with epoxy cabisol , make fairly long slope and flatten it out before the transducer

Re: Transducer Location
I will shoot some photos next time I get to the boat. Hopefully next week. I used the fairing block that came with the tranducer. It is urethane tapered shape.
Check the Furuno link for details.
