You wouldn’t drive your car everywhere in top gear.

Why do it in your boat?

• StepDrive overcomes the limitations of a single forward gear. It delivers enhanced

performance for Volvo Penta powered boats by providing a fully automatic twospeed transmission that optimises engine characteristics and boat handling.

• StepDrive simply replaces the standard centre section of the Volvo Penta 290DP

stern drive; offering the following principal advantages:


- Improved acceleration, by as much as 50%.


- Ultra smooth gear engagement and reduced creep speed; or exceptional low speed control when manoeuvring in

today’s busy waterways and crowded marinas.

- Reduced engine noise and vibration, decreased smoke and

emissions, as well as lower running costs. What’s more, StepDrive’s reduction gear

minimises inertia loading as the drive is engaged, significantly extending the life of

the driveleg’s forward / reverse clutch.

- An increase in top speed can usually be achieved by changing propeller size.

StepDrive overcomes the compromise on propeller

choice dictated by the need to reach the plane, and

achieve the best top speed.

• StepDrive is available on 290DP (models C, D and E)

stern drives when fitted to AD31, AD41, KAD32, 42, 43



• Extensive sea-trials, backed by an exhaustive 1500 hour power rig test

programme, ensure that StepDrive users can look forward to many years of

trouble-free operation.

Change up to StepDrive - a two-speed gearbox specifically for the later 290 series drive legs - from the UK’s best name in marine transmissions.

Thousands of Volvo Penta Duoprop owners could have:

• Better fuel economy


• Optimum boat performance ..plus up to 50% BETTER acceleration, making your vessel QUICKER on to the plane, and a 25% REDUCTION in creep speed.

NEWAGE PRESENTS STEPDRIVE TO COMPETITION

Congratulations to Simon Alsop of York, winner of a brand new, 2-speed PRM StepDrive gearbox in a free-to-enter competition featured in Motor Boats Monthly earlier in the year.

Stepdrive winner

Simon, pictured receiving his from Newage Transmissions’ Marine Sales Manager, Jamie Pratt, had his name drawn first from more than 200 entries to the StepDrive promotion, which was run alongside the company’s participation at the London International Boat Show in January. Simon, a 26-year-old civil engineer, intends to install his prize - along with another StepDrive unit - to his twin engined Fairline Targa 29 within the next few weeks. “StepDrives have been designed specifically for use with the Volvo diesel engines in my boat, so I am particularly pleased to have won this competition,” says Simon. “A friend of mine has another Fairline Targa, which is powered by twin V6 petrol engines. This currently outperforms my boat by quite a margin, so I’m looking forward to being able to match his performance much more closely once my StepDrives are fitted.” The novel 2-speed automatic gearboxes significantly improve boat acceleration by providing a reduction ratio of around 25% in addition to their direct drive top gear. They are installed entirely within the centre section of Duoprop units and are ideal for use with turbocharged engines such as Volvo Penta AD31 and 41 series; as well as supercharged units up to the KAD44. “From the computer simulations we’ve run, we expect Simon’s Fairline to show at least a 30% improvement in acceleration, enabling it to get onto the plane far quicker than at present,” says Mr Pratt.

Newage StepDrive Units Trialled On Venice Water TaxiImproved Manoeuvrability and Reduced Wash Provide Key Benefits

venice step drive

The ability to reduce boat creep speed and minimise damaging wash while manoeuvring in congested or restricted waterways have been key factors leading to the selection of Newage Transmissions’ StepDrive two-speed automatic marine gearboxes for pilot trials on a Venice Water Taxi.


The unit is installed in a 30 foot craft powered by a Volvo Penta AD 41 engine and will undergo extensive trials in the city’s canal network over coming months.


By providing an additional reduction ratio of around 25%, StepDrive significantly increases propeller efficiencies at low speed. As a result, fuel economy and boat handling characteristics are significantly improved while emissions and noise are reduced - making the gearboxes an ideal choice for the application.


In parallel, StepDrive’s capability to boost boat performance by around 20% will minimise travelling times between stops, as well as significantly reduce journeys from the

centre of Venice to the Lagoon or International Airport.


Developed by Newage as a retrofit product for the Volvo Penta Duoprop 290 drive leg, StepDrive is installed entirely within the centre section of the Volvo unit and, when operating in top gear, does not affect the leg's overall reduction ratio.


The gearbox has been designed both for use with turbocharged engines such as Volvo Penta AD31 and 41 series - as well as supercharged units up to the KAD 44. During acceleration, it automatically changes from low to high gear at a pre-determined engine speed, which is optimised to the individual boat and engine combination. When the boat slows again, low gear is engaged as the engine speed falls below 1500 rev/min.


According to Newage's Marine Sales Manager, Jamie Pratt: “The fact that StepDrive provides extremely smooth engagement of drive, both from rest and between ratios, is a further factor in its selection for this demanding application. The gearbox minimises shock loading on the whole driveline and therefore, wear to the drive's cone clutch. As a result, the engine operates more smoothly, under less stress and will return improved fuel economy.


“We are delighted to have been selected for these high profile trials and look forward to demonstrating the benefits of StepDrive to further users around the world during the coming months.” 

How the PRM StepDrive improves boat performance

What is StepDrive 

volvo penta ivss marine stepdrive

PRM StepDrive puts an automatic

2-speed gearbox

inside the Volvo Penta Duoprop 290 series drive leg. The effect is a massive boost in acceleration, reduced time to plane, quieter running, reduced running cost and much better close quarters handling and low speed running in restricted waterways.The reduction gear reduces the load on the engine allowing it to rev freely, utilising the engines torque and turbo abilities more efficiently. Perfect for diesel powered craft and for owners considering switching from petrol to diesel units

The installation of the automatic two speed gearbox marks the successful completion of extensive rig testing and sea trials.Newage claims dramatic improvements in the performance of boats equipped with Volvo Penta diesel engines when a StepDrive is installed. The units are self-contained gearboxes that can be retrofitted to Volvo Duoprop 290 drive legs. They are installed entirely within the centre section of the Duoprop unit and are suited for use with turbocharged engines such as the Volvo Penta AD31 and 41 series as well as supercharged units up to the KAD44.In operation, StepDrive gearboxes automatically change from low to high ratio at a pre-determined engine speed. This is optimised during installation to the individual boat and engine combination. When the boat decelerates, low gear is engaged as the engine speed falls below 1,500rpm.Installed on the Lema Clon with a 150hp AD31 engine and DP-E driveleg, the Newage Step Drive justified its maker's claims that it typically increases boat performance by 25%.'In timed test runs, some vessels have achieved 40% improvements on 0-20 knot times, said Newage's Marine Sales Manager Jamie Pratt.'However, by providing an additional reduction ratio of around 25%, StepDrive units not only boost overall performance but provide the benefits of reduced creep speed, emissions and noise when manoeuvring in busy marinas or restricted waterways.'MJ Information No: 19907
