First time winterizing 2015 23 LSV...what is this?

[cpuwhiz22]

Hey crew,

 

I upgraded from my 02 VLX to a 2015 23 LSV this year.  Absolutely love it.  Anyhow, I am winterizing the new boat now for the first time, and where my old VLX had a threaded disconnect between the exhaust manifolds, this one has a T fitting with a small hose that goes down to something on the drive shaft.  It looks like maybe some type of packing nut replacement tech, but I am not sure.  I took a couple pictures that you can see here:  https://photos.app.goo.gl/k3zTqrZaKgUoLwhJ7

 

My main question is whether this is something I need to do anything about for winterization.  Normally I just drain the system (block, exhaust, water pumps, etc.) and then run antifreeze through it.  Any help is appreciated!

And no - you don't have to do anything about it.  It self drains, everytime you take the boat out of the water

Thanks guys.  That would explain why when I disconnected the hoses nothing came out!  I guess that's one less step I need to do each year.
