Hey Dave, no, my 240 did not have shore power. Shore power on the 260 I have now was installed by you, with the connection on the aft wall of the port cockpit locker. I think this location works well- out of the weather, there is enough of a gap on the locker lid for the cord to pass without being pinched. I don't know how much work it was to install- might be some foam behind there. I guess you could also use the starboard locker, but it is much smaller and the plug would take up a lot of the space when in use.
My concern in this post the shore power connection near or at fuel locker which could be dangerous on his 240. I am trying to remember where I installed them on the 240 successfully. @patbratton send me a private message
