2004 380 DA the depth and lake temp transducer is not working and is leaking a little around the housing, I purchased a new transducer that came with a new housing, here's my question..

the tranducer was installed on the centerline of the boat, would this be from factory? I'm thinking it's goint to be hard to seal with the V at the centerline? the new transducer has a 20 degree offset for the hull angle, if it's on the centerline there's no angle

take a pic of the hull area,anytime you install things like that you use a "fairing block" that you cut to match the hull angles. If you have a 15 deg angle you cut the block at the same angle and use one inside the hull and one outside the hull. If yours does not have a fairing block you got a cheap install.

The new transducers have the internal guts on an angle to compensate for deadrise. This is the replacement ducer the OP has. So no fairing block is needed if he decides to mount that off centerline.

The current location of your ducer should be fine. I would return the B60 that you bought to replace it and simply buy a new insert for your current ducer housing. And remount the housing to stop the leak.
 
Guess the old ways of doing it right goes out the window with this new age of quick construction.The idea of fairing blocks allows a larger surface area to use waterproofing compounds. If your underwater piping is for a live well means its ok to just bore the hole and not use a fairing? Guess it ok for manufactures to use plastic thru hulls near the waterline too because its cheaper? So ,if I have this right just bore the hole, leave it as rough fiberglass(not ground smooth inside) install whatever it is your installing (without removeing all the bottom paint)and just make a mess with 5200 and hope it seals with the 1/4 or 1/2 thick surface of a transducer.? kinda stupid.

Yes that is the factory install location, centerline, just forward of the forward ER bilge pump. Mine is the same, and is dry as a bone, so you should be able to get a seal if you go the route of just replacing the factory insert.

The downside that I can see with that locationn is that is where the hull is very very thick so you are shooting through as much as 2 or 3 inches of glass. I would move it outboard from the centreline, but watch for turbulence areas caused by strainers, the tunnels, other transducers or through hulls. My Ray DSM and Raymarine adjustable angle transducer never worked well there so I moved it outboard of the stringer and its worked fine ever since.
