Types of Marine Diesel Engines
Marine diesel engines can be broadly categorized into two types: propulsion and auxiliary engines.
Propulsion Engines
Propulsion engines are designed specifically to move vessels through water. They typically feature high torque and are built to handle the rigorous demands of marine environments. Common brands include Cummins and Caterpillar, which are known for their reliability and efficiency.
Auxiliary Engines
Auxiliary engines serve a different purpose; they power non-propulsion systems such as electrical systems, water pumps, and winches. These engines are essential for the overall functionality of a vessel, ensuring that all onboard systems operate smoothly.
Factors to Consider When Buying Marine Diesel Engines
When purchasing a marine diesel engine, several factors should be taken into account to ensure you make the right choice.
Engine Type
Determine whether you need a propulsion or auxiliary engine based on your vessel’s requirements. Understanding the specific needs of your boat will help narrow down your options.
