need to replace cables. Figured out length and obtained Edson's print out of the way to do it. but of the 4 screws down thru the binnacle only 1 came out. the others are fast tight in spite of tons of lubricant and a 3 foot long screw driver as well as impact driver. no budge. Whats the next safe step?
Did you try PB Blaster?

Welcome to the whacky world of galvanic corrosion and salt air/water. You may need to drill pathways to get PB down into the threads (and repaint), or drill out the heads to remove the bolts.
I previously posted a few (YouTube) test results of different corrosion busters that you might look at. Searh for that or search YT for "Project Farm" channel and his tests.
