Volvo Penta D6 · Authorised dealer · Melbourne
Single or twin, on IPS, sterndrive or shaft. Serviced to Volvo Penta’s schedule by an authorised dealer, with a clear rundown of what’s urgent and what can wait.
Your setup
The D6 is usually fitted one of three ways, and each drive has its own service needs alongside the engine. Pick yours to see what we look after.
On an IPS boat the engine and pod work as one system, and the pod has its own service schedule alongside the engine. We service both together, then check the whole system with VODIA.

Twin installations
Many D6-powered boats run two engines, on shafts, sterndrives or IPS pods. We service both engines and both drives in the same visit, so the pair stays on one schedule.
What you get
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.
Volvo Penta’s leisure warranty expects your engine to be maintained to the operator’s manual, with records kept, and excludes faults caused by non-genuine parts or by repair work done outside Volvo Penta’s authorised network. On older D6s, Volvo Penta’s Extended Protection for leisure boats also required every scheduled service to be done by an authorised dealer or workshop. Your warranty documents set out the terms for your engine. We service to the schedule with genuine parts and record every visit. Your rights under the Australian Consumer Law apply in addition to these terms.

Something not right?
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.
A coolant temperature alarm
The engine cuts power to protect itself. Volvo Penta’s list of causes runs from low coolant and a blocked seawater intake or strainer to a slipping belt, a failed impeller or a faulty thermostat.
A charge-air temperature alarm
Volvo Penta’s advice is to have it checked, and the engine reduces power until it’s sorted. A fouled or leaking charge-air cooler is one possible cause, and worth catching early.
A “Check Engine” message
A catch-all that can mean anything from battery voltage to fuel pressure or low oil pressure. VODIA reads the stored codes, so we fix the cause rather than clear the message.
Won’t reach full rpm
Usual suspects include blocked fuel filters, water in the fuel, a fouled hull or propeller, the air supply and the cooling system. A stored fault code often narrows it down.
Smoke you haven’t seen before
Black smoke usually means not enough air. Blue or white smoke can mean the engine is running too cold, a faulty thermostat, or the oil level is too high.
Grey or milky drive oil
Water is getting into the drive, often past the propeller shaft seals. IPS drives, and some later sterndrives, will alarm on it. Get it looked at before the gears suffer.
Timing
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.

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.
Book a pre-season serviceNovember to Easter
Peak boating, and our busiest months. If an alarm won’t clear or something doesn’t feel right mid-season, call us.
Easter to July
The best time for higher-hour services, drive work and haul-outs, with the least boating missed.

Who you're dealing with
Our technicians bring Volvo Penta’s VODIA diagnostics and genuine D6 service parts to your berth, and bigger jobs come back to our Spotswood workshop.
Check the full designation on the engine plate when you book. Some ratings were used on both generations, an older IPS400 can be a six-cylinder D6-310 or a four-cylinder D4-300, and on leisure boats IPS650 is only a D6 from the 2019 update on.
D6s were fitted, as standard or as an option, to boats like the Riviera 3600 and 4400 Sport Yacht, Riviera 395 and 445 SUV, Mustang 430 Sports Coupe, Beneteau Gran Turismo 40 (2015–21) and 44, Beneteau Swift Trawler 30, Princess V39 and Jeanneau Leader 40. Some were also built with the smaller D4, so check the engine plate.
Questions
It depends on whether you have one engine or two, your drive type, and what’s due on your engine’s schedule. We confirm all of that and give you a clear quote before any work starts.
No. We service D6s at their berth or on the hardstand around Port Phillip Bay. Bigger drive work comes into our Spotswood workshop or is done during a haul-out.
On older D6s the main service is every 200 hours or 12 months, whichever comes first, with bigger items at 400, 800 and 1200 hours. Engines from the 2019 update on have longer intervals (oil and filters every 200 hours or 24 months) and show a reminder on the display before a service is due. Either way, we work to your engine’s own schedule.
Volvo Penta’s leisure warranty expects maintenance to your operator’s manual with records kept, and excludes damage from non-genuine parts or repairs outside its authorised network. As an authorised Volvo Penta dealer we service to the schedule with genuine parts and record every visit.
The rating is on the engine plate, for example D6-370 or D6-435. The updated D6 introduced in 2019 is rated D6-300 to D6-480, but the D6-300 and D6-400 names were also used on the older engine. Send us the full product designation from the plate (for example D6-440I-G) and we’ll know exactly which one you have. If you’re on IPS, note the IPS number too, since an older IPS400 can be a D6 or a smaller D4.
Yes. We service both engines and both drives in the same visit and keep a separate record for each, so the pair stays on one schedule.

Tell us about your D6 and where the boat is, and we’ll take it from there.
