I had one installed in my 2520 last winter.
I bought the rear station from an owner in Florida who removed it from a 25' C-Hawk that was being outfitted as a dive boat.
He said that the rear station was in his way for how he intended to use the boat.
The fiberglass part used by C-Hawk is nearly identical to the ones Parker installs.
The only difference is that Parker puts their wheel on top, and the motor controls on the angle.
Here is a Parker install (on a 2320 I believe)
Here is a rear station on a Parker 2820
The other difference is that mine has a soft cover on the side, while the Parker parts use a rigid deck hatch.
Replacing the soft cover with a solid hatch is a project for another day...
I assembled the major parts needed to install the rear station and delivered it to my dealer last winter when I dropped her off for winterization, and storage in their yard. They performed the install during the winter layup.
One advantage I had, was that I could specify exactly where I wanted the part located.
Notice in this photo that my rear station is mounted 18 to 20" further aft than a factory install.
I like it much better that way. :wink:
Hope this helps!
