Thanks for all the comments.
Removing "dud" equipment sounds like a good idea. The Broker has already suggested removing an ancient radar that has never worked since I have owned the boat.
I'm probably still leaning towards replacing the item, however I was planning on waiting a bit, however there is often a 2-3 month wait for electrical installations around here (West Australian economy still pretty busy).
FYI I have kept the boat in "ready to sail" condition as I just completed an 800NM coastal passage and are planning on doing a 300NM coastal trip in December. The old auto pilot really sticks out as the main item that is not up to scratch in doing these coastal trips.
Once again thanks for all the comments.
