Volvo Penta D2-75 Turbo Marine Saildrive 150S Package

Description

Command steady sailboat motor cruising with Volvo Penta D2-75 150S Package systems, engineered to power production cruising sloops, catamarans, and coastal cruisers up to 50 feet. Displacing 2,170 cc across four cylinders, this turbocharged and aftercooled diesel produces 75 horsepower at 3,000 RPM. Mechanical unit injection meters fuel with precision, delivering smooth idle speeds, clean combustion, and low vibration.

High-tensile gray cast iron forms the cylinder block, equipped with induction-hardened parent cylinder walls that resist scuffing under boost. A fresh water cooling system integrates an aluminum heat exchanger housing with a cupronickel tube bundle, aftercooler, and saildrive water intake. Dry package weight with 150S saildrive is 602 lbs, supported by a 5.8-quart stamped oil pan, bed frame, and 0.312-inch fuel connections.

Key Features of Volvo Penta D2-75

Cruising sailors buy Volvo Penta D2-75 inboard engine saildrive systems to repower modern production sailboats requiring hydrodynamic underwater profiles and minimal cabin vibration. The integrated 150S saildrive leg eliminates propeller shaft alignment issues while providing immediate thrust in forward and reverse.

• 75 horsepower rating drives displacement sailing craft with exceptional hydrodynamics.
• 115-amp 12-volt alternator with built-in charging sensor recharges house battery banks.
• Double diaphragm saildrive hull seal includes an integrated water intrusion alarm sensor.
• Charge air cooler enhances combustion density to optimize thermal efficiency across cruising speeds.
• Cupronickel tube heat exchanger protects cylinder jackets from salt scale accumulation.
• Volvo Penta D2-75 saildrive efficiency lowers hydrodynamic drag under sail in light airs.
• Flexible bed mounts isolate engine vibration from the fiberglass hull structure.
• Accessible dipstick on the saildrive leg simplifies underwater gear oil checks.

Combustion Dynamics Thermal Capacities

Coolant thermostats regulate internal temperatures between 168°F and 182°F under continuous motoring operations. The four-cylinder block develops 133 lb-ft of torque at 2,000 RPM, giving displacement sailboats power to punch through tidal headlands and harbor chop. Rated for M4 pleasure craft service, thermal heat rejection transfers 52 kW into raw water cooling circuits. Specific fuel consumption averages 224 g/kWh, burning about 1.25 gallons per hour at standard yacht cruising speeds across open coastal waters.

Exhaust Integration Bay Clearances

A water-injected exhaust elbow attaches to 3.0-inch wet exhaust hose, meeting ABYC P-1 standards for auxiliary sailboats. Mounting beds bolt straight into molded fiberglass saildrive foundations, preserving 2.0 inches of vertical clearance around the pan. Flexible mounting isolators absorb vibration from the hull.

Service Schedules Application Constraints

Direct mechanical Morse cables connect helm control levers straight to governor and saildrive shift linkages for immediate response. Operators inspect raw water seacocks, test seal alarm circuits, and monitor belt tension before getting underway. This engine package is not engineered for offshore planing hulls, commercial trawlers, or raw water cooled bilges without fresh water heat exchangers.

• Inspect saildrive water intake valve before each shift.
• Inspect and clean saildrive lower leg zincs every 150 hours.
• Change engine lube oil, leg gear oil, and filters every 200 hours.

Warranty Terms Package Manifest

Recreational buyers receive 2-Year limited warranty protection on base castings and saildrive components. The shipping crate contains the engine, 150S saildrive lower leg, hull mounting bed frame, digital instrument cluster, five-meter extension wiring harness, and a complete technical service manual.
