VETUS VH4.65 – Marine Diesel Engine 65 HP

Description

Using a naturally aspirated 2.6L inline four-cylinder configuration, the VETUS VH4.65 produces 65.3 hp at 3,000 rpm with indirect injection. The stated 22.0:1 compression ratio and EN 590 diesel requirement define the supplied fuel-system setup. Mechanical or hydraulic gearbox options, various ZF or Technodrive drive arrangements, and an SAE 4 flywheel housing establish the documented propulsion integration points.

The 536-pound dry engine uses a 12V 110-amp alternator, indirect heat-exchanger cooling with 9L coolant capacity, and a 60 mm water-injected wet exhaust. Forced lubrication holds 6.5L oil. The supplied specification lists EU RCD II and BSO II emissions ratings, alongside mechanical or hydraulic steering compatibility and a 1-3-4-2 firing order.

Key Specifications of the VETUS VH4.65 Marine Diesel Engine

• The 2.6L inline four-cylinder engine produces 65.3 hp at 3,000 rpm through naturally aspirated indirect-injection diesel operation.
• Indirect injection and a 22.0:1 compression ratio define the supplied fuel-system configuration using EN 590 diesel.
• ZF or Technodrive gearbox arrangements require propulsion-package confirmation alongside the SAE 4 flywheel housing and vessel drivetrain.
• Mechanical or hydraulic gearbox options support different listed integration approaches for the completed marine propulsion system.
• A 12V 110-amp alternator provides the stated charging output for vessels using this engine electrical-system configuration.
• Indirect heat-exchanger cooling holds 9L coolant, while the 60 mm wet exhaust defines the stated routing requirement.
• Forced lubrication uses 6.5L oil capacity, requiring engine-room access for fluid servicing and scheduled maintenance inspections.

Engine Configuration and Service Access

This VETUS marine diesel engine uses 91.1 by 100 mm bore and stroke dimensions in an inline four-cylinder configuration. The indirect-injection system, heat exchanger, wet-exhaust connection, alternator, lubrication-service points, and selected ZF or Technodrive gearbox should remain accessible after installation.

The 536-pound dry weight, cooling circuit, 60 mm wet-exhaust arrangement, mechanical or hydraulic steering compatibility, and selected drivetrain should be evaluated together. Engine-room space should allow inspection and maintenance access around the completed propulsion package.

Why Choose the VETUS VH4.65 Marine Diesel Engine

The VH4.65 marine diesel engine combines 65.3 hp at 3,000 rpm with a naturally aspirated 2.6L four-cylinder indirect-injection layout. Buyers comparing mechanical propulsion packages can assess its 12V 110-amp alternator, SAE 4 flywheel housing, mechanical or hydraulic gearbox options, and ZF or Technodrive drive compatibility. The stated 9L coolant capacity and 60 mm wet-exhaust specification support installation planning.

Installation and Compatibility Considerations

Confirm that the vessel supports the 536-pound dry weight, SAE 4 flywheel housing, selected mechanical or hydraulic gearbox, and the intended ZF or Technodrive drive configuration. Plan engine mounts, shaft alignment, fuel supply, cooling-water intake, 60 mm wet-exhaust routing, steering compatibility, 12V wiring, ventilation, and service access before installation.

Use fuel meeting EN 590 requirements. Confirm provisions for 9L coolant capacity, 6.5L oil capacity, heat-exchanger plumbing, wet-exhaust connections, gearbox servicing, and access to injection, cooling, lubrication, alternator, and exhaust-system components.

Warranty and Support

Warranty coverage should be confirmed against the current VETUS warranty policy applicable to the exact engine, purchase market, installation, and operating use. Mulmarine.com provides pre-purchase product guidance and order-related customer support. Review the applicable warranty information on Mulmarine.com before completing your order.

Before Ordering the VETUS VH4.65 Marine Diesel Engine

Before ordering, verify engine-bed dimensions, structural capacity for the 536-pound dry weight, SAE 4 flywheel-housing compatibility, selected ZF or Technodrive gearbox, shaft alignment, EN 590 fuel supply, cooling-water intake, 60 mm wet-exhaust routing, 12V electrical requirements, ventilation, steering compatibility, and professional installation planning.
