Underbody Sounders and Speedo's

[Night_Sailor]

I was wondering how many people still have these, and or use them?

I found these on my boat and plan to remove them and glass in the openings.

It seems like the depth transducer would cause a lot of drag, and the Log/Temp/Speedo would have a modest amount of drag also.

My plan is to pot in a depth transducer inside of the hull. I used this method on my sailboat and it works great, although I did have some issues with the epoxy leaking out of my paper cup mold.

As long as there are no voids (air pockets) in the hull layup, it's a great method that eliminates drag, prevents damage. I hate those transom mounts--they always break off.
