I am thinking about installing in hull transducers verses thru hull. Anyone using them have any comments? Thanks Dave
Do you have a solid glass bottom? Is there a clean interior place away from any lifting stakes on the out side, with no thru hull or exterior skin fittings in front of the planned location? Do you have an off set ducer to match the angle of the hull? Then a in-hull ducer MAY work..
What boat are we talking about? I've used them before, you do lose some power shooting through the hull, but if they're in the right location they work very good.
46 Post. I am exploring options. I have not bought the boat yet. When I get the survey, and it's out, I can put a through hull if that's the best
If you've already got the through hull I'd stick with that. Less work and as J pointed out location would be key. Much easier to determine on a new boat.
I put one on my 53 a year ago. Works well. It s about amidship maybe two feet outboard of the keel. Not sure how much power is lost and it would work for fishing but I just want to know the depth.
Go with the thru-hull. You can get an offset transducer that will eliminate the fairing block to compensate for the deadrise angle. Put one on ours a few months back, probably can use the same hole depending on the angle and location.
Thank you for the responses. Through hull it is! My current boat had through hull 1kw with raymarine 470 module
Exactly what I did with mine two years ago, works great but just for depth not sure how accurate it would be for fishing .
I ran a 45' Cabo with a 1000 watt in hull. It worked good for fishing. I didn't have any issues with it.
I mounted my shoot thru xducer by epoxing the mount. Then the xducer gets installed in the mount, filled with oil You can’t just glue the xducer to the hull
A good way to mount a transducer inside the hull is to site it first. If there are any air bubbles in the laminate, there will be a great loss of effectiveness. To make sure you have a good location, you can make a cofferdam out of a wax toilet base ring. Select a location that is not downstream of any through hulls, trim strakes, stabilizers, etc. Stick the wax ring to the inside of the hull and brace the transducer in place in the wax ring, and then fill with an oil. For permanent installations, it's usually mineral oil, but for temporary trial placement vegetable oil will work. You can't just glop it down with an adhesive, because it will have air bubbles. The time-tested method of fitting the transducer is as Pascal says; make a box and adhere it to the hull, then secure the transducer in the lid, fill the box with mineral oil, and fit the lid with a gasket. As mentioned earlier, the new pre-angled transducers are ideal for such an installation, because the whole thing can be a more compact unit.
