What this video covers
The owner of the 10-year-rebuilt fishing trawler *Brupeg* modifies the vessel’s stabilizer wing deployment system by installing sacrificial M30 threaded rod studs on the deck.0:53 These studs allow the stabilizer arms to seat directly onto the deck, replacing a manual bolting process.0:53 To facilitate the transition to electric winches for wing deployment, the crew replaces an undersized, welded-on pulley with a custom-fabricated stainless steel assembly designed to accommodate 12mm Dyneema line.6:45
Separately, the crew investigates a rhythmic whining noise originating from the propeller shaft while in forward gear at idle.11:56 After consulting with marine mechanics, they diagnose the issue as insufficient lubrication at the stern tube’s rear seal, likely caused by a blocked grease port.20:57 They resolve the noise by replacing a grease distribution manifold block with a higher-volume unit, increasing grease flow to the rear bearing.24:37 The crew also performs a gearbox oil change, switching to a mono 40 grade oil to better suit tropical operating temperatures.12:17 Regular oil analysis is planned for the future to monitor drivetrain wear.18:07
