Volvo Penta D4-260 – Marine Diesel Engine 260 HP

Description

During heavy-duty marine operation, the Volvo Penta D4-260 utilizes verified 115-amp electrical charging and closed freshwater heat exchanger thermal control. This 3.7-liter inline 4-cylinder diesel engine generates 260 horsepower at 3500 RPM, serving planing cruisers and commercial workboats. A mechanical supercharger provides instant low-end acceleration, while the turbocharger maintains efficiency at top cruise speeds.

High-pressure common-rail fuel injection delivers clean combustion with minimal noise at the helm. The engine is built on an SAE 3 flywheel housing, supporting HS63 hydraulic gears or DPH sterndrives, with a bobtail weight of 482 kg.

Key Specifications of the Volvo Penta D4-260 Inboard Marine Engine

• The 3.7-liter 4-cylinder diesel block produces 260 horsepower at 3500 RPM, offering strong power density for planing hulls.
• Supercharged and turbocharged induction delivers immediate low-rpm torque for fast planing, followed by efficient high-speed turbo boost.
• Common-rail fuel injection optimizes fuel atomization, resulting in smooth combustion, low engine noise, and clean exhaust operation.
• Closed freshwater cooling isolates the internal cylinder block from raw seawater, extending engine life in harsh marine environments.
• An integrated 115-amp alternator supplies consistent electrical current to maintain house battery banks and onboard DC navigation gear.
• The standard SAE 3 flywheel housing supports flexible coupling to HS63 hydraulic marine gears or DPH sterndrive assemblies.

Engine Performance and Engineering

Supercharging combined with common-rail fuel delivery gives this Volvo Penta inboard engine rapid acceleration characteristics. Pressure-feed wet sump lubrication protects internal components, while EVC controls ensure smooth shift and throttle control.

Why Choose the Volvo Penta D4-260 Inboard Marine Engine

Marine operators select the D4-260 marine engine for its compact 3.7-liter 4-cylinder block and 260 horsepower output. Its dual forced-induction system eliminates low-speed planing lag on heavy hulls. Closed freshwater cooling, common-rail efficiency, and versatile gear coupling make it a smart repower choice.

Mounting and Compensation Considerations

Confirm engine mount center spacing and verify that propeller shaft alignment is precise on flexible mounts. Check raw water sea strainer flow capacity and ensure exhaust riser height remains well above the loaded waterline.
