Qué cubre este vídeo
After discovering a saltwater leak in the engine bay, the crew of Zephyr performs an emergency haul-out to replace the shaft seal and coupling.0:24 A professional technician installs the new components and aligns the engine using Elibogan engine mounts, which feature adjustable bolts for precise positioning.6:56 The team uses feeler gauges to achieve a tolerance of four-thousandths of an inch between the coupling and transmission surfaces, ensuring the prop shaft and engine are perfectly aligned.7:14 During the process, the technician identifies and corrects improper bolt spacing that previously caused interference with the transmission housing.11:46 Following the installation, the boat is relaunched for a sea trial to verify the alignment and seal integrity while the hull settles in the water.14:43 The repair eliminates the leak and increases the vessel's speed by approximately 1.5 knots at 1600 RPM.17:04 Precise engine alignment and proper shaft-to-coupling fit are essential to preventing vibration and water ingress at the shaft seal.
