- 0:21Billy disconnects flooring, pipes and wiring around the Vetus diesel generator.
- 4:45The mountings come loose, but shifting the heavy generator takes considerably more effort.
- 8:44Old insulation, decayed chipboard and rust debris come out of the newly exposed cavity.
- 12:28Billy applies gel and checks the steel hull with an ultrasonic thickness gauge.
- 15:03He considers replacing thinner steel and describes his plans for a clean engine room.
The generator has to move. It still works, but Billy Petherick needs access to the steel beneath it, and that means disconnecting pipes, wiring and mountings before wrestling the weight onto the engine-room floor.
"What's Hiding Underneath This Generator?" was The Pethericks' most-watched upload of the week, reaching roughly 143,000 views. Once the machine is out of position, Billy clears away old fibreglass insulation, decayed chipboard and heaps of rust. The less photogenic side of restoring Nostalgia X gets its full turn on camera.
Then comes the check he has been worrying about: gel on the steel, an ultrasonic thickness gauge and readings that leave him more reassured about the areas tested. He says thinner sections may need cutting out and replacing. Ethan is due back to help get the generator off the boat, while Billy pictures an immaculate engine room beyond the debris.
Viewers have practical thoughts about lifting gear, steel-toe shoes and whether a replacement setup should use separate generators for daytime and overnight demand. One also describes these incremental restoration videos as a brief respite from a chaotic day, a reminder that clearing a dirty cavity can be enough of an episode.
The other uploads carry the work onwards: "Well, We've Made a Right Mess!", "Shall We Cut a Hole in the Yacht?" and "The Rust Has Eaten Right Through the Yacht". That last instalment has the most viewing momentum right now, while October's "Nobody Wanted This Yacht… So I Bought It" remains busy too.
The channel added 2,000 subscribers over the week, although daily views are running at about half their usual level. Billy's earlier reflection feels particularly relevant to this stretch of the job: he says he wishes his welding skills were better, but that the important work is best left to a professional marine welder.

I know this might seem a bit odd. But my life can sometimes be complete chaos! These daily videos are TRUE reprieve for the 10-15mins where I can take a deep breath and enjoy watching you bring this boat back to life day by day! Just wanted to let you know that there are those that appreciate your content! Cheers!
