Proven Design and Good Economy

The SDEC G128 marine engine uses a modular design with a reinforced block, a one-piece cylinder head, a forged crankshaft, and fracture-split connecting rods. All sealing gaskets are improved as well, so the engine stays stable and reliable in long-term use. In addition, the electronic unit pump system offers clean and efficient combustion and helps the engine meet Stage II marine emission rules.

Strong Power and High Torque

Thanks to its large displacement, the G128 delivers strong output with enough power reserve. Its fuel curve stays flat in common working ranges, while low-speed torque remains high. As a result, the engine gives better fuel economy. Compared with a traditional mechanical pump engine, the electronic version can save more than five percent in fuel.

Fast Response and Wide Environmental Adaptability

The G128 is built to handle tough marine tasks. It reacts fast to sudden load changes and supports steady operation across many working conditions. Moreover, it can run with lower-grade oil, fuel, and coolant when needed, which makes it suitable for harsh environments.

Easy Service and High Uptime

Most parts are shared with the earlier model, so maintenance is simple and parts are easy to find. Its long service intervals and well-proven reliability help maintain a high duty cycle. Since there are many units in the market, spare parts are widely available and maintenance costs stay low.
