Re: What are these things?
...Most instruments using through hull transducers also supply blanking plugs so the transducer can be removed for servicing. If you search around on your boat, you might find the blanking plug for it if you are lucky.
And to add to this (since you yourself admitted to being a newbie), do not attempt to remove said transducer unless the boat is out of the water, or you have said blanking plug on hand to IMMEDIATLY install in its place.
EDIT: Sorry, my post was seconds late. Looks like you're gettin' it figured out...
