Don't think any 23s came with shore power and I'd certainly think twice about mounting it forward near the bow. Most boats of any length with shorepower inlet mount them to the rear to avoid getting water over the bow in them. Just looked up the "Mfg. Pictures" in the "Boat Info." tab and I'd consider mounting the inlet at the very stern of the boat, port side, high up near the cockpit. PORT side looks to have a large locker to work with and is also the side where you galley is. Electric panel Ed mentioned could be mounted on galley wall. I guess anchor locker would work, but make sure to use the waterproof screw down cap style w/LOTS of sealant. Good luck with your project.
