Lombardini LDW1404SD Cruiser Marine Saildrive Diesel Package

Description

Meet strict coastal environmental standards with the Lombardini LDW1404SD Marine Saildrive Diesel Package built for modern performance cruising sailboats. Displacing 1.4 liters across four inline cylinders, this naturally aspirated diesel generates 40 brake horsepower at 3600 RPM. Overhead cam unit injection burns just 2.0 gallons per hour at cruising speeds, delivering exceptional fuel efficiency during offshore passages.

Cast iron alloy forms the cylinder block to suppress engine noise and vibration under load. The saildrive leg housing uses marine-grade cast aluminum protected by sacrificial zinc anodes. A cupronickel shell heat exchanger handles raw seawater cooling loops. Dry package weight equals 315 lbs. Sump capacity measures 3.4 quarts with 5/16-inch fuel ports.

Key Features of Lombardini LDW1404SD

Naval architects buy Lombardini LDW1404SD inboard engine systems to power performance cruising yachts seeking efficient horizontal thrust without shaft logs. The four-cylinder saildrive configuration delivers whisper-quiet motoring when wind conditions die on open ocean passages.

• Saildrive lower legs eliminate traditional propeller shaft stuffing boxes and strut alignment complications
• Four-cylinder engine balance eliminates cabin vibration during prolonged motor-sailing periods
• Unit pump injectors deliver precise mechanical fuel metering without sensitive electronic control modules
• Lombardini LDW1404SD Deluxe instrument panels display engine RPM, coolant temperature, and hour meters
• Double rubber hull diaphragm seals incorporate visual and audible water ingress warning sensors
• Cupronickel tube heat exchangers resist seawater pitting with replaceable sacrificial zinc pencils
• Saildrive leg water intakes pull cooling water deep below turbulent aerated surface waters
• Top-mounted oil dipstick and filter locations permit clean servicing inside confined machinery spaces

Dynamic Torque Thermal Boundaries

Overhead cam unit injectors spray fuel at 200 bar to produce 62 lb-ft of continuous torque at 2000 RPM. Closed fresh water systems hold block temperatures between 160°F and 180°F. Seawater exchangers dissipate 2,600 BTU per minute through the saildrive exhaust hub, maintaining a lean 240 g/kWh fuel efficiency rate.

Hull Aperture Saildrive Clearances

The saildrive leg installs through a reinforced hull aperture adhering to ABYC P-1 standards. Heavy rubber clamping rings secure the drive leg to structural fiberglass beds without transmitting engine vibration into yacht accommodations. Saildrive fairing boots glue flush against the hull bottom for minimal hydrodynamic drag.

Saildrive Protocols Forbidden Operations

Single-lever mechanical controls afford positive gear engagement and throttle modulation when picking up mooring buoys. Hull diaphragm cavities must be checked for moisture before departing port. This saildrive package is not engineered for planing motor yachts, dry exhaust stacks, or continuous operation past 3600 RPM.

• Check saildrive lower gearcase oil condition each shift
• Drain fuel water separator collection bowls every 50 hours
• Replace saildrive sacrificial zinc collar anodes every 12 months

Warranty Statement Shipping Inventory

Cruising owners receive a 2-Year limited factory warranty covering base engine and saildrive leg components. The wooden export container holds the marine engine, complete saildrive leg unit, hull mounting clamping ring, Deluxe instrument panel, wiring loom, and official installation manual.
