Lombardini LDW702SD Yacht Marine Saildrive Diesel Package

Description

Tired of messy bilge packing glands and propeller shaft misalignment in coastal sailboats? The Lombardini LDW702SD Yacht Saildrive Package produces 18BHP from a 0.7L Inline-2 diesel block at 3,600 RPM. Overhead FOCS unit injectors demand clean water-free diesel fuel. Dual hull gasket beds require precise torque checks during installation to guarantee absolute watertight integrity.

Cast iron parent-bore cylinder construction ensures high structural stability across engine beds, while an aluminum cylinder head saves essential weight. Overhead camshaft timing drives internal FOCS unit pump 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.

Key Features of Lombardini LDW702SD

Commercial charter fleet managers buy Lombardini LDW702SD yacht saildrive packages to repower coastal cruising sloops and light sailing catamarans. The saildrive system executes inland waterway narrowboat propulsion engine replacements and auxiliary refits where low vibration protects hull joinery.

• FOCS unit pump injectors inside cylinder heads eliminate high-pressure lines and reduce fire hazards.
• Natural aspiration keeps machinery space ambient temperatures cool during long transit cycles.
• SeaProp 60 saildrive lower leg reduces drag compared to traditional propeller shafts and struts.
• Cast iron engine blocks resist bore distortion under continuous cruising throttle settings.
• Dedicated saildrive leg water intake slots supply cooling seawater into tubular heat exchangers.
• Continuous P1 rating supplies 16BHP at 3,300 RPM for prolonged coastal motor passages.
• Intermittent P3 rating yields 18BHP at 3,600 RPM for docking against stiff tidal currents.

Dynamometer Bench Test Load Performance

Dynamometer cell evaluations verify continuous output of 16BHP at 3,300 RPM with peak intermittent power reaching 18BHP at 3,600 RPM under load. Naturally aspirated exhaust gas pyrometer readings stay below 1,120°F before raw seawater injection. Coolant temperatures stabilize at 180°F through copper-nickel heat exchanger tubes. Crankcase lube oil pressure tracks at 48 PSI at continuous rated speed. Intermediate saildrive housing flange runout remains under 0.0003in TIR across operational static tilt angles up to 15°.

Field Operation Saildrive Service Protocols

Single-lever cockpit controls shift saildrive clutches with smooth positive dog engagement requiring under 3 lbs throw force. Do not specify this 18BHP saildrive unit for heavy steel displacement barges or vessels requiring offshore platform survival craft propulsion power capacities.

• Change engine crankcase oil and replace spin-on oil filter cartridges every 250 operating hours.
• Check saildrive gear lube oil condition and inspect hull diaphragm seals every 100 operating hours.
• Replace primary fuel filter elements and saildrive zinc anodes every 500 operating hours.
