The StepDrive overcomes the limitations of a single forward gear. It delivers enhanced performance for Volvo Penta powered boats by providing a fully automatic two speed transmission that optimises engine characteristics and boat handling.
The 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.
The StepDrive is available on 290DP (models C, D and E)stern drives when fitted to AD31, AD41, KAD32, 42, 43
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
StepDrive is manufactured to the highest engineering standards by Newage-PRM, one of Europe's leading names in driveline technology. The unit has been rig-tested to confirm durability.
