What this video covers

The crew of SV Delos installs a Nani N480 diesel engine into the port engine bay of their custom-built aluminum catamaran.1:18 The engine, a turbo-intercooled mechanical unit with a TM 345A hydraulic gearbox, serves as the primary power source for the vessel's hybrid propulsion system, which also incorporates a 25-kilowatt electric motor.5:28 During the installation, the team faces tight tolerances, with less than half a centimeter of clearance between the engine and the hatch opening.0:22 To navigate the space, they tilt the engine to reduce its effective length and use a forklift combined with manual adjustments to lower it into the bay.15:33 The installation process requires precise alignment of the engine mounts, stern tube, and prop shaft, alongside planning for the exhaust system and raw water intake to ensure proper fall and anti-siphon height.9:43 The project also involves fabricating a complex connector plate for the boat's structural wire rigging.11:44 Careful planning of component placement, including the gearbox and belt access, ensures future serviceability.10:30
