Ce que couvre cette vidéo
The crew of the vessel *Brewpeg* performs maintenance on the boat’s Kort nozzle and propeller while hauled out at Port City Fabrications in Gladstone.0:02 To address pitting on the nozzle’s leading edge caused by barnacle abrasion, the crew applies Jodafair epoxy fairing compound, sands it to a smooth airfoil profile, and coats it with Jodamastic 90 epoxy etch primer, a chlorinated rubber tie coat, and black antifouling paint.0:44 The Kort nozzle, which features a 52-inch mouth tapering to a 46-inch propeller diameter, increases thrust for slow-moving vessels by accelerating water flow and provides physical protection for the propeller against debris.3:46
The crew then applies Propspeed to the propeller, a process requiring precise timing to ensure chemical bonding between the etching primer and the clear silicone topcoat.7:49 They use a specialized curved roller to ensure full coverage on the propeller blades.16:16 Final haul-out tasks include installing a new ball valve on a skin fitting, cleaning the engine room bilge, and draining water tanks to reduce weight for the lift.24:00
