High Reliability and Strong Base

The SDEC SC7H marine engine offers reliable power for long hours at sea. It uses a strong alloy cast-iron block, forged crankshaft, one-piece cylinder head, and rear gear housing. These parts make the engine very durable and stable. In addition, it can run more than 20,000 hours before a major overhaul. Therefore, operators can trust the engine for long-term use and heavy tasks without worrying about breakdowns.

Strong Power and Low Fuel Use

The SC7H features a four-valve design and high fuel injection pressure to improve air intake and fuel burning. As a result, it works efficiently, produces cleaner exhaust, and saves fuel. Moreover, its high power density provides extra power reserve for sudden load changes. The engine reacts quickly when the vessel needs fast acceleration. Meanwhile, the fuel curve stays flat in normal working conditions, which helps reduce daily fuel use and lowers operating costs.

Compact Design and Low Noise

The SC7H has a modular, compact design that is easy to fit in small engine rooms. In addition, it is lightweight and saves space. The engine also uses low-noise gears and a vibration-reducing main bearing support. Therefore, it runs quietly and produces less vibration, creating a more comfortable work environment for the crew.

Flexible Options and Wide Adaptability

The SC7H offers various optional features, such as different starting methods, output interfaces, exhaust pipes, and oil-filling points. Moreover, it works well in different climates and can start in temperatures as low as –15°C. Because of these choices, the engine can meet many marine tasks and adapt to changing sea conditions.

Easy Maintenance and High Uptime

The SC7H integrates parts and reduces wear items, which lowers failure risks. The anti-wear valve system and fracture-split connecting rods extend service life. In addition, maintenance is simple and fast. As a result, the engine provides high uptime, lower service costs, and reliable operation for vessels over time.
