Volvo Penta D1-30 – Inboard Diesel Engine 30 HP

Description

Review compact propulsion interfaces around the Volvo Penta D1-30, rated at 28.4 hp from a naturally aspirated 1.13L inline three-cylinder diesel at 3,200 rpm. Its mechanical marine gear, modified SAE 5 flywheel housing, and MS15A, MS15L, or S-Drive compatibility define the listed drivetrain choices. The in-line injection pump, closed fresh-water cooling, and 115-amp alternator should be assessed with fuel, exhaust, charging, and service-access requirements before installation.

The 320-pound dry engine uses EN 590 or ASTM D975 diesel, pressure-feed lubrication with 3.5L oil capacity, and a water-cooled elbow exhaust arrangement. Coolant capacity is listed at 4.1L. The supplied specification identifies EPA Tier 3, BSO II, and RCD II emissions ratings, alongside mechanical steering compatibility and a 1-3-2 firing order.

Key Specifications of the Volvo Penta D1-30 Marine Diesel Engine

• The 1.13L inline three-cylinder engine produces 28.4 hp at 3,200 rpm through naturally aspirated diesel operation using an in-line injection pump.
• An in-line injection pump and 23.5:1 compression ratio define the supplied fuel-system configuration using EN 590 or ASTM D975 diesel.
• MS15A, MS15L, or S-Drive compatibility requires drivetrain confirmation alongside the stated mechanical marine gear arrangement.
• A modified SAE 5 flywheel housing defines the listed engine-to-transmission interface for compatible propulsion-package planning.
• The 115-amp alternator provides the stated charging output for vessels using this engine electrical-system configuration.
• Closed fresh-water cooling holds 4.1L coolant, while the water-cooled elbow defines the specified exhaust-water arrangement.
• Pressure-feed lubrication uses 3.5L oil capacity, requiring engine-room access for scheduled maintenance and fluid inspection.

Engine Configuration and Service Access

This Volvo Penta marine diesel engine uses 77 by 81 mm bore and stroke dimensions in an inline three-cylinder, four-stroke layout. The injection pump, cooling components, water-cooled elbow, alternator, lubrication-service points, and selected mechanical gear or S-Drive should remain accessible after installation.

The 320-pound dry weight, mechanical steering compatibility, cooling circuit, wet-exhaust configuration, and selected drive interface should be evaluated together. Provide clearance for inspection, fluid changes, and maintenance of the complete propulsion package.

Why Choose the Volvo Penta D1-30 Marine Diesel Engine

The D1-30 marine diesel engine combines 28.4 hp at 3,200 rpm with a naturally aspirated 1.13L three-cylinder configuration and in-line injection pump. Buyers comparing compact inboard or saildrive packages can assess its MS15A, MS15L, or S-Drive compatibility, mechanical marine gear, 115-amp alternator, and modified SAE 5 flywheel housing. The supplied 320-pound dry weight supports engine-room planning.

Installation and Compatibility Considerations

Confirm that the vessel supports the 320-pound dry weight, modified SAE 5 flywheel housing, mechanical marine gear, and selected MS15A, MS15L, or S-Drive configuration. Plan engine mounts, shaft or saildrive alignment, fuel supply, cooling-water intake, water-cooled elbow routing, controls, alternator wiring, ventilation, and service access before installation.

Use fuel meeting EN 590 or ASTM D975 requirements. Confirm provisions for 4.1L coolant capacity, 3.5L oil capacity, mechanical steering compatibility, and access to the injection pump, cooling system, exhaust components, and lubrication-service points.

Warranty and Support

Warranty coverage should be confirmed against the current Volvo Penta warranty policy applicable to the exact engine, purchase market, installation, and operating use.
