Your setup
Which Scania setup do you have?
Scania marine engines work in everything from motor yachts to pilot, patrol and fishing boats, usually on shafts through a marine gearbox. Pick the one closest to your boat, or see what we look after behind the engine.
Scania’s pleasure craft rating is built for boats that run at power only in short bursts and up to 500 hours a year, so time and long lay-ups matter as much as hours. We service the engine and its sea water side together.
- Engine oil and filters
- Fuel filter and water-separating prefilter
- Sea water pump impeller
- Sacrificial anodes
- Air cleaner and vacuum indicator check
- Coolant protection check
- Drive belt and leak checks
- Shaft seal and coupling check
Twin installations
Twin Scanias, one visit.
Many Scania-powered boats run a pair, from Maritimo motor yachts to police search and rescue boats. We service both engines and both gearboxes in the same visit, so the pair stays on one schedule.
- Both engines and both gearboxes serviced in one visit, at your berth where possible
- Side-by-side checks, so a difference between engines shows up early
- A separate record for each engine, the history buyers and surveyors ask to see
- Haul-out work planned with your yard
What you get
You’ll know exactly where your engines stand.
Every service ends with a plain-English rundown. Each item is marked done, keep an eye on, or needs attention, so you can see what’s urgent and what can wait. Anything beyond the service is quoted first.
- A separate record for each engine and gearbox
- Kept for your survey, insurance and resale history
- What’s due next, so you can plan around the season
Under factory warranty?
If your Scania is still under its factory warranty, check the terms for what they say about servicing, parts and records, and tell us when you book so we can service it to suit. Either way, we record every visit. Your rights under the Australian Consumer Law apply in addition to these terms.

Something not right?
Signs your Scania wants attention.
Many problems give a warning first. If you’ve noticed one of these, it’s worth a look before it turns into a lost weekend, or a lost day’s work.
A high coolant temperature alarm
On a current DI13, Scania gives normal running as 81 to 90°C with a heat exchanger. Depending on how the engine is set up, the alarm can come with reduced power or a shutdown. On a well-used engine it commonly traces to a worn impeller, a fouled heat exchanger or scale in the cooling circuit.
A water-in-fuel alarm
On engines with a water sensor in the prefilter, Scania’s standard response is an alarm and a 30% torque reduction, so the engine loses power. Scania warns water in the fuel can cause serious engine problems, so drain the prefilter and find where it’s coming from.
Black smoke and sluggish under load
Usually restricted air, a fouled charge air cooler, a tired turbo or an overloaded propeller. A red vacuum indicator on the air cleaner points to the filter. We find the real cause before replacing parts.
Rubber bits in the sea water strainer
Vane fragments mean the impeller is breaking up, and the missing pieces can block a cooler downstream. Scania’s advice is that frequent impeller changes mean the sea water intake needs better cleaning.
Charging lamp on while running
Scania’s first check is the alternator drive belt. If the lamp stays on after that, it’s likely the alternator or the electrical system, and worth sorting before the batteries go flat.
Odd gauge readings or alarms that come and go
Salt air is hard on connectors, wiring and sensors. Intermittent alarms often trace back to corrosion or chafed wiring rather than the engine itself, but each one is worth finding.
Timing
Book around the boating season.
A little planning means the boat is ready on the first good weekend, not the third.
78%
of maritime incidents reported in Victoria in 2024–25 were vessel breakdowns, most of them engine failure or running out of fuel.

Pre-season service
Book before the rush. November to Easter is our busiest period, so a service in late winter or early spring has the boat ready for the first good weekend.

Peak boating, and our busiest months. If an alarm won’t clear or something doesn’t feel right mid-season, call us.

The best time for higher-hour services, coolant changes, gearbox work and haul-outs, with the least boating missed.
Who you're dealing with
Independent Scania specialists, looking after Melbourne boats since 1995.
We’re not a Scania dealer. We’re an independent marine workshop that services and repairs Scania engines at your berth or in our Spotswood workshop, with genuine or quality aftermarket parts.

- Authorised Twin Disc dealer and ZF Marine Service Point
- Also authorised for Volvo Penta and Yanmar
Scania marine engines we service, old and new
The code on the engine plate tells you the engine. In DI13 507M, for example, DI13 is the 13-litre, 507 is the performance code and M means marine. Scania’s XPI common rail reached its marine V8 in 2015 and the 13-litre in 2017, so a DI13 or DI16 can be an earlier or later engine. Send us the full code and serial number when you book.
Scania engines power boats like the Maritimo X60 and M70 motor yachts, along with commercial and government workboats around Australia. Some of these boats were also offered with other engines, so check the engine plate.
Questions
What Scania owners ask us
How much does a Scania service cost?
It depends on the engine, whether you have one or two, and what’s due on its schedule. We confirm all of that and give you a clear quote before any work starts.
Are you a Scania dealer?
No. We’re an independent marine workshop. We service and repair Scania engines with genuine or quality aftermarket parts, and we’re an authorised Volvo Penta, Yanmar and Twin Disc dealer, and a ZF Marine Service Point.
Do I need to bring the boat to you?
No. We service Scania engines at the berth or on the hardstand around Port Phillip Bay. Bigger jobs come into our Spotswood workshop or are done during a haul-out.
How often does a Scania need servicing?
Scania’s operator’s manuals set the schedule by hours, and at least once a year. On an older DI12 the oil change is every 400 hours. On a current DI13 it depends on sump size, fuel use and oil grade, from 400 to 850 hours. We work to your engine’s own manual and record every visit.
Which Scania do I have?
The engine plate carries a code like DI13 507M, and the serial number is also stamped on the block. Send us both, since a DI13 or DI16 can be an earlier engine or a later XPI common-rail one. Older boats may have a DI12 or DI14.
I have twin Scanias. Can you do both at once?
Yes. We service both engines and both gearboxes in the same visit and keep a separate record for each, so the pair stays on one schedule.
How do I book?
Use the booking form at the top of this page or call (03) 9399 5888. We aim to reply within 1 business day.
Ready when the weather is.
Tell us about your Scania and where the boat is, and we’ll take it from there.
