Engine Room Build: From Bare Aluminum to Fully Outfitted Man-Cave

Engine Room Preparation and Filling

• 🛠️ The engine room, often cramped and hot, is the heart of a modern cruising boat, requiring meticulous work.
• 💡 Brian began working on the engine room months prior, dry-fitting all equipment, brackets, pumps, and engines before welding.
• 🧩 Total Boat fairing compound was used to fill voids on either side of the keel, creating a level surface for bilge pumps.
• 💧 Holes were drilled between compartments to allow water to flow to a single bilge pump location, effectively creating a new floor.

Epoxy Coating and Priming

• ✨ After filling and sanding, epoxy was poured over the filler to create a smooth, level surface in the bilge.
• 🎨 The team thanked Total Boat for providing products that aided in the build, including the fairing compound and epoxy resin.
• 🖌️ The next steps involved cleaning, drying, priming, and painting the engine room floor.
• 🚀 The goal was to create a smooth, level floor to prevent dirty water accumulation in hard-to-reach corners.

Painting and Soundproofing

• 🎨 The engine room floor was primed with three coats of primer, followed by bilge paint for a clean, white finish.
• ⚠️ A mishap occurred with white bilge paint splattering, requiring careful cleanup with the correct thinner.
• 🔊 Venus sound insulation was installed, featuring different densities of foam to cancel noise effectively.
• 🏠 Thicker insulation was used on bulkheads and the roof, while thinner material was applied to exterior-facing walls to direct sound away from the boat.

System Installations

• 💧 The fresh water pump and water heater were installed and tested, with no leaks found.
• ⛽ A complex fuel distribution and filtering manifold was assembled on a workbench and then installed, allowing for running the engine from either tank and transferring fuel with filtration.
• 📊 Amar fuel flow sensors were installed to measure fuel consumption, connecting to a NEMA 2000 network.
• 🚢 In the starboard engine room, insulation was not applied to the sides as it would only house pumps and air conditioning, not a diesel engine.

Engine Installation and Alignment

• ⚙️ The diesel engine was reinstalled into the engine room using a forklift, a process that had been done before.
• 🔧 The primary focus after engine installation was accurate alignment of the clutch using feeler gauges to meet strict tolerances.
• ✅ The engine room build involved multiple stages, including preparation, filling, epoxy work, painting, soundproofing, and system installations, culminating in the engine's permanent placement.
