Has anyone installed an inhull transducer in the engine compartment of a stepped hull formula.I have a 2004 382 and I would like to mount the transducer in the engine compartment.

We installed one today in a 2000 312,the factory transducer was in a hole cut thru the liner, we dug it out and glued the new transducer there.

I don't think you have a liner, Rob.

...smooth-off a spot, and glue it down with either resin or 4200/5200. Make sure to not have any air-voids underneath the ducer. Then go looking for some thin water to check it out.

We use the epoxy that Lowrance or Humminbird supplies,resin is also good. Just don't use silicone sealer,it kills the signal for some reason.

I have a 2006 292 which is a twin stepped hull like your 382. The factory depth finder didn't work very well and I replaced the thru hull transducer with one compatible with the SC5000 smartcraft display. The factory tranducer is located under the hinged step entering the cuddy cabin and this is where I installed the new one. I researched this and you MUST install the transducer forward the the steps in the hull or you will not get a good reading when on plane. The factory transducer was smaller in diameter than the new one I was installing. There IS a liner, so I had an experienced shop with the right tools enlarge the hole in the liner. The new transducer has a housing that I siliconed to the hull and filled with mineral oil. The transducer attaches to the housing and is sealed with an o-ring. The signal shoots through the mineral oil and hull. Works GREAT, even running 70 mph! I would not install your transducer in the engine compartment unless you don't care to see the depth while underway.

Yup, no problem mounting near the transom for a non-stepped hull. The issue with steps is they aerate the water and this causes interference with the sonar. The transducer needs a solid path when sending the sound waves to the bottom and back. That's why any gaps between a liner and hull or air bubbles in the epoxy can cause problems too.
