The Heart of the Blue Homeland Beats Domestic: We Analysed Domestic Military and Commercial Marine Engines for You

We examined the domestic power sources of Mavi Vatan. 1100 HP BMC Mavi Batu, Tümosan's 460 HP TMSNX7 engine and Erin Motor's technical details are in our news.

Domestic Marine Engines

The Turkish defense and machinery industry is making a strategic transformation by extending its independence in engine technology, achieved in land vehicles, to the Blue Homeland (maritime territory). The maritime sector, dominated by imported brands for years, is now preparing to navigate with high-performance power units developed by Turkish engineers. These domestically produced marine engines, used in a wide range of applications from flagship defense projects to civilian commercial vessels, are not just machines, but symbols of strategic independence.

At yuzde100yerli.com, we've reviewed domestic marine solutions for you, from massive 1000 horsepower power units to fuel-efficient, long-lasting boat engines, based on their official technical documentation. Here's a showcase of the power of BMC Power, Tümosan, and Erin Motor on the seas.


BMC Power

BMC Power, which set out with the goal of becoming Türkiye's power group hub, is introducing engines developed to military standards to the maritime sector through a "Marinization" (adaptation to sea conditions) process. The technical data we examined proves that the company is a "heavyweight" player not only in auxiliary class engines but also in main propulsion systems.

Levend Engine

BMC Power Levend Marine

General Information About Levend Engines
Levend, one of BMC Power's most notable projects, proved its worth in July 2025 when it was integrated into the "Tow Truck-25" tugboat in the inventory of the Istanbul Shipyard Command. This integration enabled the engine, which successfully towed the TCG Savarona, a legacy of Gazi Mustafa Kemal Atatürk, to be used in the tugboat. Contrary to popular belief, this engine is not a small unit; it is a 12.82-liter, high-torque, heavy-duty marine powerhouse. The threefold increase in the tugboat's towing power is a result of this high displacement and torque.
