    Your setup

    Which D6 setup do you have?

    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

    Twin D6s, one visit.

    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.

    • Both engines and both drives serviced in one visit, at your berth where possible
    • VODIA across both engines, the EVC system, helm stations and joystick (where fitted)
    • A separate record for each engine, the history buyers and surveyors ask to see
    • Drive work and lifts 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 drive
    • Kept for your warranty and resale history
    • What’s due next, so you can plan around the season

    Servicing and your Volvo Penta warranty

    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?

    Signs your D6 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.

    • 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

    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.

    1. August to October

      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.

    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

    What D6 owners ask us

    How much does a D6 service cost?

    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.

    Do I need to bring the boat to you?

    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.

    How often does a D6 need servicing?

    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.

    Will servicing with you keep my Volvo Penta warranty valid?

    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.

    Which D6 do I have?

    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.

    I have twin D6s. Can you do both at once?

    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.

    How do I book?
