OK. Since my last posting I spoke to customer service at GW and visited Southeaster Marine in Richmond. As a reminder, I had to replace the cockpit deck drain on the port side and the fish box drain on the starboard side.
Up to fairly recently, the deck drain fitting screwed into a 90 degree El fitting that has a hose barb end. Even tho' the part you see on the deck looks like a thru-hull fitting, the threads are not the same. Problem is, the deck fitting that screws in is no longer available. It has been replaced by a one piece fitting - part # 11-101.
The fish box drain fitting is part # 11-066 and as luck would have it, my Grady dealer had one in stock. This part screws into the 90 degree el that is attached to the end of the drain pipe. This is actually a sink drain made by Forespare. Their part # is SW-1.

Customer service at GW recommended cutting thru the bottom of the compartment under the helm seat. I thought about this long and hard and studied the port side to get an idea of how effective this would be. With the drawers and cabinet frame out of there, you have pretty good access but try as I might, I couldn't see or do anything back where the fish box drain is.
I spoke with my dealer about this and the parts manager said if you don't have arms like an orangutan, you can't do it. Well, I don't. I tried a few other ideas but finally opted to cut a 6" opening in the bottom of the fish box. Boy am I glad I did.
As I suspected, there is virtually no room to work if one cuts out the bottom of the box under the helm seat. Secondly, there was a fair amount of standing water under the fish box. The way GW foams in the hull, water gets trapped between the hull/side wall and the foam. It can't drain back to the bilge pump. I found 2 pockets of water on the starboard side and one on the port side.
With the hole in the fish box, I was able to pull the drain hose up where I could see the El and get the old drain fitting out. As I was looking at the threaded El, I could see that it was not perpendicular to the fitting. This put some twisting force on the fitting and ultimately caused it to break. I had to loosen the clamp and straighten the El in order to thread the new fitting on.
After lots of mumbling and grumbling and some cursing (ok, lots - it's not Sunday) I finished the project. It was a lot more difficult than I expected. I always seemed to be working at arms reach and able to get only one arm/hand in there. Regarding the fish box drain - if I'd have cut a hole anywhere else, there is no way I could have done the repair. SFC, I strongly suggest you take the port side drawers and liner out so you can evaluate your ideas knowing it's even tighter on the starboard side.
Sorry for the long post but I hope it provides some of the insight I was looking for when I asked for help.
