Yes. Did this on my O'Day 25 recently. Very easy if the mast is down.Borrow or buy an electricians snake and use it to pull a fresh wire in. Chief

Keary, you can't. It is solid in there between the overhead pan molding and the deck. The builder put those wires in before he put the boat together. You will have to bring the wire down through the deck and inner molded liner and then run the wire along the bulkhead and then run it up under the side of the molding all the way back to your fuse panel. If you're 25 was like my 26, then you will have to run it down the port side and then cross in the rear somewhere to get to your fuse panel underneath the companionway But you're not going to be able to put it between the ceiling of your cabin and the deck. You can use the trim to hide the wires. It is better to bring in forward of the bulkhead so it is invisible from the salon at leastYeah the connector is to the port side of the mast. The plug and mast wires are fine for 33 years old. How do you run wire between the glass cabin ceiling and the fuse panel?
