Screwdriver probes rotted bulkhead wood inside boat cabin
What this video covers
A rotten engine-room bulkhead discovered after removing the fuel tank on the Lagoon 450 Parlay Revival drives most of this episode, filmed in Phuket.0:45 Pulling the tank revealed it had been sitting directly on bare plywood for 14 years; moisture in the wood had corroded the tank's exterior while diesel bug had pitted the interior.3:21 A welder named Chun cut a template, then TIG-welded a new aluminium bottom onto the tank in the cabin — a repair Colin describes as stronger than the original.7:20 A pressure test at 1 psi initially appeared to hold, then failed; Jamie traced the leak to a loose bung, not the welds.17:59 With the bung replaced, the tank held 1.5 psi for 24 hours.21:04 The bulkhead repair involved cutting back rotten 15 mm plywood to dry material and tabbing in a new marine-ply section with epoxy.12:15 A separate update covers a lithium battery reassessment: YouTuber Will Prowse physically cut open a "Game Changer" battery and shared findings with Colin, prompting Colin to reconsider the batteries aboard; Battle Born's response is pending.Watch The solar system is being expanded to 6.5 kW using seven 710-watt bifacial panels across an extended arch and hardtop, with eight dedicated charge controllers and a Lynx distributor.21:32 Rubber isolation between a fuel tank and its plywood cradle is critical — its absence caused corrosion from both sides simultaneously.3:12
