Default How do you remove a thru hull transducer???

Bought a boat about a month ago. Its got a thru hull transducer. From underneath the boat you would see a hole about 2" in diameter that has been filled with some shiny hard glassy dark material. Does anyone what this material is and how to remove it?

I'm thinking this thing is leaking and I would like to remove it in its entirety and have the hole filled.

A plastic thruhull transducer could be described as you did. Look inside. A thru hull transducer will have a 1/4" wire coming out of it, and may have a screw on cap that will allow you to remove it. If you think its leaking, dry the area with a hair dryer, and sprinkle some powdered soap around it. Launch the boat and watch. Even a slow seep will show in the soap powder. If its a patch job instead of a transducer, and it doesn't leak, think twice about a serious glass job. If its a leaking patch, and you want a transducer, investigate why there isn't one there now. It could have been in a cavitation area.

If you're going to have a pro fill the hole, just let him remove the transducer also. It's much easier for someone to handle the entire job than to have to follow someone else who may have screwed up.
