I have a '02 Formula 292 with Latham steering. I am interested in adding the drive shower hoses to the brackets already mounted to the top of my drives. It is my understanding that the hoses thread into the hole on the top of the drive bracket. I was looking at my boat today and noticed that the hole is not threaded on my setup. Is that normal?

They were threaded on both of mine...post a picture someone here may have a good idea how to fix issue, or tap it

I wanted to do the same thing but mine were not threaded either
