Lombardini – NEW Lombardini LDW 1404M 35hp Marine Diesel Engine & Gearbox

Lombardini LDW 1404M 35hp Marine Diesel Engine & Gearbox – Professional Overview

The Lombardini LDW 1404M is a four-cylinder marine diesel engine configured as part of a complete propulsion package. With a rated output of 35hp (26kW) and 1.4L displacement, it provides a compact diesel power solution for marine repower applications.

The supplied package combines the engine with a Technodrive TMC40 gearbox, flexible engine mounts, control panel, and wiring loom. This integrated configuration allows the main propulsion components to be supplied together rather than requiring the buyer to source each component independently.

The engine uses a freshwater heat exchanger cooling system, while the package is supplied new and includes a full Lombardini warranty according to the provided product specification.

An alternative gearbox configuration can also be supplied, with pricing available on request. This provides additional flexibility where the vessel’s existing drivetrain or installation requirements call for a different transmission arrangement.

For customers considering other propulsion solutions, the marine diesel engine category provides a useful reference point for comparing engines and complete repower packages across different horsepower ranges.

Compatibility, Applications, and Technical Context

The Lombardini LDW 1404M marine diesel engine is designed for inboard marine propulsion applications where a compact four-cylinder diesel package is required.

Its 35hp output makes it relevant to vessels that require moderate diesel propulsion power, although final engine suitability depends on the vessel, existing propulsion system, gearbox configuration, shaft arrangement, and installation requirements.

The standard package includes a Technodrive TMC40 gearbox, providing an integrated engine-and-transmission configuration for suitable installations.

The engine can also be supplied with an alternative gearbox when required. This can be particularly useful during repower projects where the replacement engine needs to work with a specific propulsion arrangement.

Before ordering, buyers should confirm the existing engine’s dimensions, gearbox configuration, shaft alignment, mounting arrangement, and required power rating to establish compatibility.

Cooling System and Engine Construction

The Lombardini LDW 1404M uses a four-cylinder configuration with a 1.4L cylinder capacity. The product specification identifies the cooling system as freshwater cooled through a heat exchanger arrangement.

Heat exchanger cooling separates the engine’s internal cooling circuit from the external marine cooling water system. For a marine propulsion installation, this forms an important part of the engine’s operating configuration.

The package includes flexible engine mounts, which are supplied as part of the standard configuration. Proper engine alignment and mounting remain essential during installation to ensure that the engine and gearbox operate correctly within the vessel’s propulsion system.

The supplied control panel and wiring loom complete the principal engine-control components included with the package.

Gearbox and Repower Configuration

The standard Lombardini LDW 1404M 35hp package includes a Technodrive TMC40 gearbox.

Having the gearbox supplied with the engine provides buyers with a matched propulsion package rather than purchasing an engine separately and sourcing a transmission afterward.

An alternative gearbox option is also available on request. This allows the package to be considered for repower projects with different drivetrain requirements.

When replacing an existing marine diesel engine, gearbox compatibility is an important consideration. Buyers should compare the existing gearbox, shaft alignment, mounting position, reduction requirements, and available engine space before selecting the final configuration.

Control Equipment and Installation Components

The package includes a control panel and wiring loom, together with flexible engine mounts.

These components are important when installing a replacement engine because the propulsion system requires appropriate connections between the engine, vessel controls, and electrical system.

The supplied flexible mounts are intended to form part of the engine installation arrangement, while the control panel and wiring loom provide the equipment necessary for the engine’s control and monitoring system.

For a repower project, buyers should establish whether the existing vessel controls and electrical installation can be retained or whether modifications will be required.

Warranty and Long-Term Ownership

The Lombardini LDW 1404M 35hp Marine Diesel Engine & Gearbox is supplied new with full Lombardini warranty, according to the supplied product information.

A manufacturer-backed warranty provides an important ownership consideration when purchasing a new marine engine, particularly for buyers replacing an older propulsion system.

Regular servicing and correct installation remain important for maintaining reliable marine engine operation. Buyers should follow the applicable manufacturer maintenance requirements and ensure that installation work is completed correctly.

Why Choose This Lombardini Marine Diesel Package?

The Lombardini LDW 1404M 35hp Marine Diesel Engine & Gearbox brings several key repower components together in one package.

The four-cylinder 35hp diesel engine provides the propulsion power, while the Technodrive TMC40 gearbox supplies the standard transmission arrangement. Flexible mounts, control equipment, and the wiring loom are also included.

This configuration can simplify the process of sourcing a replacement propulsion system for suitable vessels. The availability of an alternative gearbox further expands the range of installations that can be considered.

For boat owners replacing an older inboard diesel, the combination of engine, gearbox, mounting hardware, controls, and warranty makes this package particularly relevant to complete repower projects.

Who This Product Is Best For

The Lombardini LDW 1404M 35hp marine diesel engine package is intended for boat owners, marine engineers, boatyards, and other buyers planning an inboard diesel repower.

It is particularly suitable for buyers looking for a complete 35hp marine diesel engine and gearbox package rather than an engine-only configuration.

The package can also suit customers who need to replace an older inboard diesel while upgrading the propulsion system with new mounting, control, and transmission components.

Final suitability should always be established against the vessel’s required horsepower, installation dimensions, gearbox requirements, shaft arrangement, and existing propulsion system.

Technical Specification
