The tower on my 20 SF works great!!

No reason it would not work on a 23!!
The way it is over the T-top makes for a smooth ride!

It easily comes on and off as needed with one person.
It is held in place with two sockets in the splash well then
two 1/4-20 stainless bolts on the frame of the top...
If you need more pics I will be happy to share.
