Volvo Penta D4 · Authorised dealer · Melbourne
Volvo Penta D4 service, brought to your berth.

Your setup
Which D4 setup do you have?
The D4 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 Aquamatic sterndrive (the classic DPH, or the DPI from 2019) the drive leg has its own schedule, and the rubber bellows that seal it are a safety item. We service the engine and the drive in the same visit.
- Engine oil and filters, genuine Volvo Penta
- Fuel filters, water trap and bleed
- Seawater pump impeller
- Drive oil change and condition check
- Bellows inspection, renewed on schedule
- Steering, trim and hydraulic hose checks
- Duoprop propellers, seals and drive anodes
- Exhaust pipe and anode corrosion check
Twin installations
Twin D4s, one visit.
Many D4-powered sports cruisers run two engines, on sterndrives, IPS pods or shafts. 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 D4s, Volvo Penta’s Extended Protection for leisure boats also required scheduled services 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 D4 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 “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.
A “Water in fuel” alarm
Water has collected in the separator on the fuel filters. Volvo Penta says not to keep running with water in it, as it can damage the engine. If it keeps coming back, it’s worth finding where the water is getting in.
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, and Volvo Penta lists a leaking propeller shaft seal as the possible cause. Newer drives can show a “Water in drive oil” alarm. 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.

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.

Every D4, old and new
Check the full designation on the engine plate when you book. The D4-300 name was used on both generations, and on IPS boats an IPS400 can be a four-cylinder D4-300 or a six-cylinder D6, so check the engine plate.
D4s were fitted, as standard or as an option, to boats like the Riviera 3600 Sport Yacht (IPS), Beneteau Gran Turismo 38 and 40, Beneteau Antares 30S and 36, Jeanneau Leader 36 and 40, and Nimbus 365 Coupé. Many were also built with D6s or petrol engines, so check the engine plate.
Questions
What D4 owners ask us
How much does a D4 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 D4s 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 D4 need servicing?
On older D4s 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 D4 do I have?
The rating is on the engine plate, for example D4-260 or D4-300. The updated D4 introduced in 2019 is rated D4-145 to D4-320, but the D4-300 name was also used on the older engine. Send us the full product designation from the plate (for example D4-300A-E) and we’ll know exactly which one you have. The letter after the rating usually shows the drive: A for Aquamatic sterndrive, I for inboard and D for IPS.
I have twin D4s. 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.
