Well worth the trouble
Hi Alan,I added stern rail seats to my '94 23.5 in 2004 as well. Like Ed, I paid about $650 from Hunter. They were not easy to install. On the earlier 23.5's (like ours) there are no backing plates for the stern rail seats. Glassing in the 2 big chunks of aluminum (provided) on the inside of the transom was the most challenging. It's pretty tight back there, especially for a big guy. Once those were in, I found out the stainless backing plates for the gunales were too wide to fit. A call back to Hunter and they sent me the correct ones. After mounting the port side stern rail I was on a role - it fit like a glove. However, the starboard side must of bent in shipping, or it slipped in the welding jig. Another call to Hunter and they reccomended that I try to cold set (bend) it before resorting to shipping it back. I was able to tweak it back into shape with the help of a couple of big, closely spaced trees to hold one end while I tugged on the other (big guy was an advantage here!). I figured I had nothing to lose since I could always send it back if something went wrong. After several attempts, I was able to get it back into shape without any structural damage. I was able to add pelican hooks to my lifelines without changing the length.Mission accomplished. It seems like they add 2 feet to the boat. They are a great addition.
