Mercury Diesel 2.0L 150HP Inboard Engine – Reliable Mid-Range Marine Power
Introduction
The Mercury Diesel 2.0L inboard engine is a compact yet powerful solution designed for small to mid-sized vessels that demand reliability, efficiency, and low maintenance. With a rated output of 150 horsepower, this engine is part of Mercury’s versatile 2.0L marine diesel series, offering a perfect balance between fuel efficiency, performance, and durability.
This engine is ideal for recreational boats, sportfishing vessels, small yachts, and workboats, providing smooth propulsion and responsive handling. Designed with Mercury’s modern engineering standards, it integrates advanced turbocharging, fuel injection, and electronic monitoring to ensure optimal performance under a wide range of marine operating conditions.
Product Description
The Mercury Diesel 2.0L 150HP is a 4-cylinder, 4-stroke, turbocharged inboard diesel engine. It features a robust cast iron engine block and high-strength aluminum cylinder head, engineered to withstand the harsh marine environment while maintaining a lightweight design for easy installation in smaller engine compartments.
Equipped with a turbocharger and aftercooler, the engine provides enhanced torque and efficiency, ensuring smooth acceleration and reliable cruising at various speeds. The engine utilizes a common-rail fuel injection system, which optimizes fuel delivery and combustion efficiency, improving power output while reducing emissions and fuel consumption.
The engine is cooled via a closed-loop freshwater system with a heat exchanger, protecting the engine from corrosive seawater while maintaining optimal operating temperature. All routine service points—oil filter, fuel filter, dipstick, and coolant access—are conveniently positioned to allow easy maintenance, even in tight engine rooms.
With a focus on smooth and quiet operation, the engine is fitted with resilient mounts and vibration-dampening components, reducing noise and vibration levels onboard. Mercury’s global support network ensures access to spare parts, technical support, and maintenance resources, giving boat owners confidence in long-term reliability.
