I think my airmar thru hull transducer is going bad on my Raymarine MFD. Anybody ever swapped one out while the boat is in the water? I'd just be changing the "insert", not the tube.
That is a thruster, we have a similar one on our Camano. Also I doubt your transducers compatible.Tpbrady is that a stern mounted thruster? Back to the subject I'm getting ready to install a 740 gps in place of an older Garmin and I'm not sure I'll be able to use the threw hulls I have or if I'll need to pull an put new ones in. Is there anyway to tell what I have by what's in the bildge I know I have some blank pieces of plastic to go in if I pull the transducer out.

True, if he has the interchangble type he should be able to just buy another insert I believe?Most transducers are made by Airmar and sold with different cable connectors for the Electronics brand. If yours is an Airmar, you can purchase an adapter cable here: Transducer Parts | Blue Heron Marine Electronics

I had a Garmin 2006c. And a separate Garmin dept/fish finder.What was your old Garmin unit that you replaced? That will give you an idea which transducer you have installed?
Two of the bigger one.
Most modern transducers are powerful enough to just be mounted inside and shoot through the hull...no special ducer needed.
When I was doing my bottom over..I just yanked the old ducer and filled in the hole....never even planned on putting the new "through hull" ducer through the hull as I really don't need the sensitivity of a fishfinder in a trawler.

It is on an angle and it has a twin on the other side of the bildge. What is a tilted element. I have plastic pieces about 6" long that look like they go into this unit as a blank. It would be nice if I could somehow ping the wires to find out which one goes to which sonar or gps.The big one looks like an Airmar transducer, with a water speed paddle wheel. There should be a number on a tag on the cable somewhere, usually close to the td. It could be a 600 or possibly a 1000 watt, or a tilted element unit. Unless it is on a fairly flat (horizontal) surface I would guess it is a tilted element unit, lack of an inside fairing block anyway.
The sonar is a Garmin 240The smaller one is probably a temperature transducer. The larger one has no apparent through hull cross bolting and looks like an older combination fathometer / speed transducer. If it has the correct plug end, it may plug into your new unit and work ok. Garmin 2006 chartplotter was designed to be used with a sonar unit. Somewhere on your boat there is most likely a sonar module, probably a Garmin GSD20. The transducer may be plugged into that. I'm not familiar with a Garmin 740 and don't know if it will run off the GSD20. That would be a question for Garmin Customer Service, but I would think you would want to connect the transducer directly to your new unit. But as someone else has pointed out, it won't give you the performance of a new dual frequency transducer. Your Garmin 740 is capable of up to 1 KW operation and will provide you much greater sensitivity and definition. I would replace it at your earliest opportunity.
