Lombardini LDW702M Inboard Shaft Marine Diesel Engine Package

Description

Low fuel consumption pairs with minimal dry weight in the Lombardini LDW702M Inboard Diesel Package, producing 18BHP from a 0.7L Inline-2 engine at 3,600 RPM. This 4-Stroke compact diesel fits shallow motor boxes in traditional wooden work skiffs. Overhead FOCS unit injectors demand clean diesel stock. Operators must inspect fuel filters on schedule to prevent injector nozzle clogging.

Monobloc cast iron provides structural rigidity across parent-bore cylinder walls without wet liner shifting risks. Dual overhead camshaft geometry operates internal FOCS unit injectors without external high-pressure fuel lines. A 12V negative ground system features a 1.2 kW starter motor and 40A marine alternator. Dry engine mass measures 161 lbs within an engine stance measuring 18.7in long, 18.5in wide, and 20.8in high holding 0.42 gal of oil.

Key Features of Lombardini LDW702M

Commercial boatyards buy Lombardini LDW702M inboard diesel packages to repower inland canal craft and traditional wooden launches. This drivetrain executes commercial workboat diesel engine repower operations while keeping mechanical systems simple and maintenance costs low.

• FOCS unit pump injectors inside the cylinder head eliminate external high-pressure fuel lines.
• Naturally aspirated air induction keeps machinery box heat loads minimal during prolonged transits.
• Aluminum alloy cylinder heads drop overall weight to preserve shallow water vessel draft.
• Closed-circuit heat exchangers maintain thermal balance via gear-driven seawater pumps.
• Technodrive TMC 40P mechanical marine gearboxes ensure positive cone clutch engagement.
• Continuous P1 commercial duty rating supplies 16BHP at 3,300 RPM for sustained motoring.
• Intermittent P3 rating yields 18BHP at 3,600 RPM for fast docking in narrow river locks.

Dynamometer Test Bench Load Ratings

Laboratory dynamometer testing verifies 16BHP continuous output at 3,300 RPM and intermittent output of 18BHP at 3,600 RPM under continuous marine loads. Naturally aspirated exhaust gas pyrometer readings stay below 1,120°F at the water injection riser. Closed-circuit cooling water settles at 180°F through copper-nickel tube cores. Engine lubrication oil pressure holds at 48 PSI at rated cruising speeds. Crankshaft journal runout maintains under 0.0003in TIR across transmission output flanges under static driveline inclination angles up to 15°.

Field Operation Skiff Service Protocols

Cable control linkages actuate with low friction requiring under 3 lbs of lever throw force at the helm station. Do not install this lightweight 18BHP propulsion unit in heavy steel cargo barges or vessels that require offshore platform survival craft propulsion power levels.

• Change engine oil and install fresh screw-on oil filter cartridges every 250 operating hours.
• Inspect heat exchanger sacrificial anodes and check transmission oil levels every 100 operating hours.
• Replace fuel filter cartridges and inspect water pump neoprene impellers every 500 operating hours.
