Another successful repower delivered!

Our team recently supplied the main engine repower of a prawn trawler in Newcastle, replacing the existing engine with the Isuzu Japan factory marinised UM6HK1TCX, producing 350HP @ 2800rpm.

In the marine industry, the word reliability is often used. With Isuzu, it's more than a marketing term—it's a reputation earned over decades of proven performance in some of the toughest commercial environments.

For operators, reliability means more than just uptime. It means confidence to head offshore, lower operating costs, easier maintenance, and an engine that's built to perform season after season.

Proud to help another commercial vessel return to work with dependable Isuzu power.
