Lombardini LDW1003M Inboard Shaft Marine Diesel Engine Package

Description

Experience smooth auxiliary propulsion in small engine compartments with the Lombardini LDW1003M Inboard Shaft Package. This 4-Stroke Inline-3 diesel outputs 27BHP at 3,600 RPM across a compact 1.0L displacement. Unit pump injectors inside the cylinder head demand clean fuel without water contamination. Operators must prime fuel supply lines with attention after filter swaps to maintain consistent starting performance.

High-strength cast iron forms the parent-bore cylinder block to provide durability while an aluminum alloy cylinder head cuts overall engine mass. Overhead camshaft construction operates the integrated FOCS unit pump injectors directly for precise mechanical fuel timing. A 12V negative ground system pairs a 1.2 kW starter motor with a 40A marine alternator. Dry engine mass measures 187 lbs within a base envelope measuring 22.1in long, 18.5in wide, and 20.8in high with a 0.63 gal oil pan.

Key Features of Lombardini LDW1003M

Commercial boatbuilders buy Lombardini LDW1003M inboard shaft packages to equip small work punts and auxiliary sailing vessels. This compact package solves commercial workboat diesel engine repower requirements where machinery spaces cannot fit heavy cast iron engines.

• Patented FOCS unit pump injectors inside the cylinder head eliminate external high-pressure fuel lines.
• Natural aspiration removes turbocharger heat radiation inside small confined motor boxes.
• Aluminum alloy cylinder heads drop overall weight to reduce hull displacement drag.
• Closed-circuit tubular heat exchangers employ neoprene seawater pumps for temperature stability.
• Technodrive Twin Disc TMC 40P mechanical transmission provides dependable cone clutch engagement.
• Continuous P1 commercial rating supplies 24BHP at 3,300 RPM for steady auxiliary cruising.
• Intermittent P3 rating yields 27BHP at 3,600 RPM for fast harbor docking maneuvers.

Dynamometer Bench Test Output Ratings

Dyno load cells record continuous output of 24BHP at 3,300 RPM alongside intermittent output of 27BHP at 3,600 RPM. Naturally aspirated exhaust gas temperatures reach 1,120°F before entry into the water-jacketed exhaust elbow. Fresh cooling water maintains 180°F through copper-nickel heat exchanger tubes under steady load. Crankcase oil pressure holds at 48 PSI at rated engine speed. Static crankshaft runout stays within 0.0003in TIR when mounted at operational driveline tilt angles up to 15°.

Field Operation Compact Service Guidelines

Mechanical helm control levers actuate throttle and transmission linkages with smooth feedback under 3 lbs pull resistance. Do not install this ultra-compact 27BHP package in heavy displacement steel hulls or commercial vessels requiring sustained high-bollard towing capacity.

• Drain engine lube oil and replace screw-on oil filter elements every 250 operating hours.
• Inspect heat exchanger sacrificial zinc anodes and gearbox oil levels every 100 operating hours.
• Replace primary fuel filter elements and inspect seawater pump impellers every 500 operating hours.
