In 1962, S. Murugan, our founder, started SM Engineering Works in Kanyakumari, Tamil Nadu, to provide servicing and maintenance of marine engines and gearboxes.

In 1975, we extended our network to the neighbouring states of Kerala and Karnataka.

In 1985, we became the authorized service partner for Ashok Leyland Engines and Gearboxes. After this monumental tie-up, the year 2002 saw the establishment of our branches in Kanyakumari, Tuticorin, Kollam, and Kochi.

In 2004, we identified the requirement for high-power engines and hydraulic gearboxes in the marine fishing industry in India. In 2005, our promoters went to China to form a strategic alliance with the Chinese manufacturers.

In 2006, we signed an agreement with Hangzhou Advance Gearbox Group Co. We also started SM Marains to cater to the industry's ever-growing need for various hydraulic gearboxes and engines.

In 2007, we established a network of branches in the states of Andhra Pradesh and Maharashtra.

By 2011, we established a presence in all coastal cities in India.

In 2012, we developed our own marine power-take off product – SME PTO, when our parent company SM Engineering Works celebrated its 50th anniversary.

In 2013, SM Marains decided to focus more on customer engagement. This is why we launched a customer care toll free number, becoming the first representative of the Indian marine industry to do so.We started our Customer Meet Programme in 2015.

In 2016, we opened a marine engine assembly unit SM Mukki Marine Engine Gearboxs Private Limited in Nagercoil. This has been established in technical collaboration with Sinotruk.
