Seacraft Hull Construction & mounting transducer

[RS]

I didn't take pics of the assembly. To answer your Q's: The transducer is too big to fit into a 4" pvc pipe, so I made it with a 4" connector glued edge to edge to a 4" cleanout with 5200.

The connector has a lip on the inside. That lip along with a few scraps of glued in pvc holds the transducer upright and horizontal to the water. The pvc connector is angled to fit the hull dead rise.

I drilled a hole the size of a wine bottle opening in the top of the cleanout plug. I passed the transducer plug out though that hole. I also drilled through a wine cork to accommodate the size of the transducer cable. I cut a slit in the wine cork so that I could insert the cable.

The pvc assemble was glued to the hull with 5200. The transducer was dropped in and the pvc filled with mineral oil (baby oil). The top of the cleanout is screwed on and the cork/cable is inserted into the hole on top to prevent oil from splashing out and water from getting in.
