Marine diesel is all we do.
Specialist mechanics for premium recreational vessels across Brisbane, the Gold Coast and Sunshine Coast.
A specialist workshop for owners who don't compromise on their vessel.
Hewartson Diesel Services was built on a simple idea, recreational marine diesel deserves specialists, not generalists. Our customers own boats from 30 to 120 feet: serious investments, weekend memories, and often a lifetime of dreams.
We focus exclusively on the marine diesel engines and generators that power those vessels. That focus is why owners, captains and brokers across South East Queensland refer us by name.
The people behind every job.
A tight-knit crew of marine diesel specialists, in the workshop and on the water.
Deep expertise, deliberately narrow focus.
We service, diagnose, repair and repower recreational marine diesel engines and the generators fitted alongside them, motor yachts, sportfishers, flybridge cruisers, sailing yachts and long-range trawlers from 30 to 120 feet.
Our specialty is Volvo Penta, Cummins, Yanmar and Caterpillar. From routine servicing through to full engine repowers, every job is delivered with manufacturer-spec workmanship and straight communication.
