Scania marine engines we service
Our diesel technicians work across the Scania marine range — propulsion and auxiliary — for both pleasure and commercial vessels. If your model isn't listed, call us; we almost certainly cover it.
Scania Servicing & Scheduled Maintenance
Keep your Scania marine engine reliable and efficient with scheduled servicing carried out by experienced diesel technicians. We follow sensible service intervals for DI09, DI13 and DI16 engines and log everything so your maintenance history stays current. Regular oil, filter and cooling attention is the cheapest insurance against an expensive failure offshore.
Diagnostics & Electronic Fault-Finding
Modern Scania marine engines run sophisticated electronic management and XPI common-rail fuel systems, and intermittent faults need proper diagnosis rather than guesswork. Our technicians read engine fault codes, interrogate the management system and trace electrical, sensor and fuel-side issues to their root cause. You get a clear explanation of what is wrong and a fixed quote before any work proceeds.
Repairs, Overhauls & Rebuilds
From a single injector to a complete engine rebuild, we carry out mechanical and electronic repairs on Scania marine diesels of all sizes. We handle top-end work, full overhauls and ground-up rebuilds, plus cooling, fuel, turbo and injection repairs — always with an honest assessment of repair versus replace. Where it makes sense, a rebuild can give you a near-new engine for a fraction of repower cost.
Parts, Repower & Installation Support
We source genuine Scania and quality aftermarket parts to suit your engine and budget, and we are not tied to one supplier. If your engine is beyond economical repair we can advise on repower options and support a clean installation — and as authorised Twin Disc and ZF dealers, we can supply and match the gearbox too. Honest advice first — we will tell you when a rebuild beats a replacement and when it does not.
Mobile Service, Commercial & Survey Support
We come to you across Port Phillip Bay and greater Melbourne for servicing, breakdowns and inspections where lifting the engine out is not practical. For commercial operators we work to keep your vessel in survey and minimise downtime, and we carry out pre-purchase and insurance inspections so you know exactly what you are buying or insuring. Call us to arrange an on-site visit or a workshop booking.

Why boat owners choose us
Scania marine service — your questions answered
Do you service Scania marine engines even though you are not a Scania dealer?
Yes. We are an independent marine workshop, not a Scania dealer, but our technicians are highly experienced diesel-engine specialists who service, diagnose, repair and rebuild Scania DI09, DI13 and DI16 marine engines. You get specialist knowledge without dealer-network overheads. Call (03) 9399 5888 to discuss your engine.
Can you get parts for a Scania marine engine?
We can. We source genuine Scania parts as well as quality aftermarket alternatives, and because we are independent we are not locked into a single supplier. That lets us balance cost, availability and quality for your particular engine. Tell us your model and serial number and we will quote the parts you need — call (03) 9399 5888.
Do you offer mobile service for Scania engines around Port Phillip Bay?
Yes. We provide mobile servicing, breakdown response and inspections across Melbourne and Port Phillip Bay for jobs that do not require the engine to come back to the workshop. Larger overhauls and rebuilds are usually best done at our Spotswood workshop. Call us to arrange the right option for your vessel.
Should I rebuild my Scania engine or replace it?
It depends on the engine's condition, hours and how the rest of the vessel stacks up. We give you an honest assessment after inspection — a well-executed overhaul or rebuild can deliver near-new reliability for far less than a full repower, but sometimes a repower is the smarter long-term call. We will lay out both options with costs so you can decide. Request a quote or call (03) 9399 5888.
Can you diagnose electronic and common-rail faults on newer Scania engines?
Yes. Newer Scania marine engines use electronic management and XPI common-rail fuel systems, and we have the equipment and experience to read fault codes, analyse live data and trace electrical, sensor and fuel-side problems to their source. You will get a clear diagnosis and a fixed quote before we carry out any repair.
How quickly can you look at my Scania engine?
Turnaround depends on the job and parts availability, but we prioritise commercial operators and vessels that are out of action. Call (03) 9399 5888 with your engine model and the symptoms, and we will give you a realistic timeframe and the next available booking. For breakdowns we will do our best to get to you quickly.
