Diesel Engineering

Servicing, repairs and overhaul

Diesel engines are the heart of every vessel and therefore form the backbone of Marine Power Systems Diesel Engineering services.

Our workshop in Kopu, near Thames, serves as the New Zealand repair facility for Steyr Motors and we provide mobile service for these engines throughout New Zealand. Within the local area we also provide service for Caterpillar, Cummins, Doosan, MAN, John Deere, and Scania engines.

As well as our marine services, we also offer servicing for standby and prime power generator and industrial diesel sets.
