Daihatsu marine diesel engines are among the most widely used auxiliary engines in the global merchant fleet. From bulk carriers and tankers to container ships and general cargo vessels, Daihatsu 4-stroke medium-speed engines power generators, cargo pumps, and onboard utilities across thousands of vessels worldwide.

We serve chief engineers, fleet managers, and ship management companies across India, the Middle East, Southeast Asia, and Europe with fast, reliable parts dispatch — including emergency 24–48 hour global delivery.

The Alang Advantage — Why India for Daihatsu Parts?
Marinexa is based in Bhavnagar, Gujarat — the city adjacent to Alang ship recycling yard, the world’s largest ship breaking facility. Each year, hundreds of vessels are beached at Alang, many equipped with Daihatsu-powered generator sets. Components removed from these vessels are inspected, reconditioned, and made available at prices 30–60% below OEM cost.
This gives us a sourcing advantage that no European or Middle East parts supplier can match: a continuous, local supply of quality Daihatsu parts at competitive prices, with the ability to ship globally within 24–48 hours.
