Taking delivery of your first IPS-equipped flybridge can feel very different from moving a conventional shaft-drive boat. The controls are intuitive, but the system should still be understood before you attempt a tight berth or set off on a longer passage.
What Volvo Penta IPS actually is
IPS stands for Inboard Performance System. It combines electronically controlled engines, steerable drive units beneath the hull and forward-facing, twin counter-rotating propellers. The propellers work in relatively undisturbed water and pull the boat through it, rather than using fixed shafts, separate rudders and rear-facing propellers.
IPS is fitted to many modern motor cruisers, including models in the
Prestige range. The installation can improve manoeuvrability, onboard space and efficiency, although the result depends on the hull, engines, loading and operating conditions.
Why the joystick helps when berthing
On a twin-engine IPS installation, the electronic control system coordinates steering angles, gear selection and engine thrust. Moving the joystick can make the boat travel ahead, astern, sideways or diagonally, while twisting it can rotate the boat.
That makes close-quarters handling easier, but it does not remove the effects of wind, tide, momentum or poor visibility. A standard joystick should not be assumed to hold the boat automatically in one position. Station-keeping requires Volvo Penta’s optional Dynamic Positioning System, while Assisted Docking is a separate feature that can compensate for wind and current where fitted.
Spend time practising away from traffic before using the system in a crowded marina. Learn how quickly the boat gathers way, how it responds from each helm and how the bow and stern move in a crosswind. Burton Waters’
RYA training centre offers training on owners’ own boats, which can be particularly useful after changing vessel or propulsion type.
Follow the correct service schedule
IPS maintenance is model-specific. Do not rely on a blanket rule that every drive needs the same work annually. Use the operator’s manual and service protocol for the exact engine and drive serial numbers.
Typical checks can include drive oil, propellers, anodes, seals, corrosion protection, steering components, software and the Electronic Vessel Control system. Service intervals have changed across IPS generations, so work should be based on the manufacturer’s schedule rather than habit.
Damage to a propeller or underwater drive should be inspected promptly, especially after grounding, striking debris or picking up a line. Burton Waters’
boatyard and engineering team includes Volvo Penta technicians who can carry out servicing, fault finding and repairs.
Habits to build before departure
Allow the displays and Electronic Vessel Control system to complete their start-up checks before selecting gear. Confirm that steering, throttles and joystick control are available at the active helm, and investigate warning messages rather than repeatedly clearing them.
Check engine fluids, bilges and visible signs of leakage before leaving. Understand whether your boat has separate trim tabs or interceptors, because these are not the same as steering the IPS drives. Keep the operator’s manual aboard and make sure everyone who may take the helm knows how to select stations and stop the engines safely.
Check the insurance position
There is no universal rule that every insurer treats IPS differently from shaft drive. You should nevertheless describe the boat, engines and propulsion accurately and check cover for underwater machinery, accidental impact, recovery and any survey or maintenance conditions. Burton Waters can discuss available
insurance options, subject to the insurer’s terms.
Frequently asked questions
Can I steer normally at cruising speed?
Yes. The wheel and throttle controls remain the main controls underway. Joystick functions vary by installation and software.
How often should IPS be serviced?
Follow the schedule for your exact model and operating hours. Annual inspections may be sensible, but fluid, filter, seal and other replacement intervals are not identical across all systems.
Can I continue on one engine after a fault?
A twin-engine boat may retain limited propulsion, but the correct response depends on the failure. Follow the alarms and operator’s manual, avoid using a damaged drive and seek assistance where safe control is uncertain.
