I am trying to install a depth transducer inside the hull and do not know if the depth log is broken or the transducer is not working through the hull. Does anyone know if the hull is cored of if it is solid??

Does anyone have a depth transducer mounted inside the hull (not a through hull)??

Pure, unadulterated, solid fiberglass. What are you putting between the transducer and the hull (as in some sort of fluid or gell)?

Per my conversaation with Standard Horizon, I am using the wax from a toilet ring seal! I have used other methods before but this one sonded convincing!

I suspect that the instrument itself is damaged. The previous owner did not tell me the truth on a number of other fronts.

Assuming the transducer id waterproof and you have enough cable or portable battery, connect the equipment and hang the transducer over the side and see if you can get a reading. If that works, you might need to find a different mounting spot. Good idea to be sure the device works before running all the cable or mounting permanently. I bought one on the net and couldn't get it to work, had to send it back for a different model. Haven't had time to try the replacement yet.

Yes, this is EXACTLEY what I should have done.....but didn't. Now I am going to have to fish the wire out and try it over the side.

Where were you about 18 hours ago when I needed to be reminded of this???!!!

"I am using the wax from a toilet ring seal"

Works like a champ for me... 'dollop' of the wax smooshed down to maybe 1/8" thickness beween the transducer and the hull.

OK, that settles it. I think the receiving unit must be damaged. Probably time for a new one.

What style 'puck' does your unit have? A 'flatiron' shape designed for transom use?

About our hulls being solid or cored, I always read they were solid here on the forum. Then I had a crack in the bottom of my hull repaired a couple weeks ago and when my marina owner ground out the fiberglass, he said he found a foam core in there. It was dry and in good shape, so I didn't need to worry about saturation. Anyone else heard about the foam core?

You and Mike Humphries have the two experimental carbon fiber, foam cored hulls Frank Butler originally built for the BMW-Oracle syndicate. (They should've kept them.)

I had some deck damage where the boat was pushed under the dock and the deck was torn away down to the hull. The hull, below the deck joint and down at least 8 inches, is wood cored.

I put in a thru-hull and filled in two old holes, and the hull was solid fiberglass about 3/8" thick.

Likewise. I did find foam between hull and cockpit liner in the transom, but that doesn't really qualify as "coring".

I think we need some clarification from Bill Holcomb... BILL??
