Volvo Penta D1-30 Packaged Inboard Marine Diesel Engine

Description

Satisfy international harbor emissions rules via Volvo Penta D1-30 Marine Engine packages, designed to repower cruising sailboats, motor sailors, and displacement trawlers up to 35 feet. Displacing 1,130 cc across three cylinders, this naturally aspirated diesel generates 27.3 horsepower at 3,200 RPM. Cam-driven mechanical unit injectors produce clean fuel atomization, low smoke emissions, and smooth torque throughout the operating band.

High-tensile gray cast iron forms the monolithic cylinder block, equipped with induction-hardened parent cylinder walls that resist scuffing. A fresh water cooling system integrates an aluminum heat exchanger housing with a cupronickel tube bundle and bronze sea water pump. Dry packaged weight is 291 lbs, supported by a 3.7-quart stamped oil pan, SAE 6 housing, and 0.312-inch hose barb fuel fittings.

Key Features of Volvo Penta D1-30

Cruising sailors buy Volvo Penta D1-30 inboard engine packages to replace obsolete raw-water cooled engines inside compact sailboat engine compartments. The balanced three-cylinder configuration delivers dependable auxiliary propulsion without adding excess weight to the boat structure.

• 27.3 horsepower rating propels displacement sailing craft at hull speed in head seas.
• 115-amp 12-volt alternator with built-in charging sensor recharges house battery banks.
• Rigid cast iron engine block suppresses vibration across low and high RPM ranges.
• Cupronickel tube heat exchanger protects cylinder jackets from salt scale accumulation.
• Electric glow plugs initiate rapid combustion down to freezing bilge temperatures.
• Volvo Penta D1-30 auxiliary efficiency lowers fuel burn on extended coastal passages.
• Flexible rubber engine mounts dampen three-cylinder reciprocating pulses to protect stringers.
• Front-mounted sea water pump allows quick neoprene impeller replacement through hatch doors.

Combustion Dynamics Thermal Capacities

Coolant thermostats regulate internal temperatures between 168°F and 182°F under continuous motoring operations. The three-cylinder block develops 50 lb-ft of torque at 2,200 RPM, giving displacement sailboats power to punch through tidal headlands and harbor chop. Rated for M4 pleasure craft service, thermal heat rejection transfers 20 kW into raw water cooling circuits. Specific fuel consumption averages 238 g/kWh, burning about 0.48 gallons per hour at standard yacht cruising speeds across open coastal waters.

Exhaust Integration Bay Clearances

A water-injected exhaust elbow attaches to 2.0-inch wet exhaust hose, meeting ABYC P-1 standards for auxiliary sailboats. Mounting brackets adjust across 16-inch to 18-inch stringer centers, preserving 2.0 inches of clearance below the oil pan. Flexible elastomer mounts absorb vibration from the hull.

Service Schedules Application Constraints

Direct mechanical Morse cables connect helm control levers straight to governor linkages for immediate response. Operators inspect raw water strainers, check oil levels, 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 sea water intake strainer before each shift.
• Inspect and clean heat exchanger zincs every 150 hours.
• Change engine lubricating oil and spin-on filter elements every 200 hours.

Warranty Terms Package Manifest

Recreational buyers receive 2-Year limited warranty protection on base castings and mechanical components. The shipping crate contains the packaged engine, vibration isolators, digital instrument cluster, five-meter extension wiring harness, oil extraction pump, and a complete technical service manual.
