A propulsion device where the propeller operates on the water surface behind the transom of the boat.
Typically the propeller is only 50% immersed at operating speed.
The propeller shaft angle is low – typically around 6º - so offers more efficient thrust angle.
The propeller is specially designed to operate in this half-in / half-out manner and is more efficient than conventional propellers at speeds over 25 knots.
4www.q-spd.com31/12/2013
Appendage drag is reduced by more than 50% No prop shaft, skegs and rudders as on conventional drives
Only half the propeller is immersed
Only a fraction of rudder in water at speed
No entrained water to carry, as with Water Jets
Surface propellers are ventilated – D0 Not Cavitate.
Less Fuel Burn ..… Higher Speed .… Shallow Draft

Q-SPD Surface Drives was established in 2001. Based in Auckland, New Zealand, they have developed an extensive range of models to suit a wide range of vessel sizes and applications
10 to 36 meters and up to 3000hp
Q-SPD is not just another surface drive. Q-SPD boasts many features that other surface drives cannot.
Q-SPD is the “SOLUTION”

Higher Speed
Less Fuel
Lighter Weight
Better Acceleration and Cruise Speeds
Better Manoeuvrability
Easy Installation
Less Maintenance
Smooth and Quiet Operation
User Friendly
12www.q-spd.com31/12/2013
Lightweight Composite Construction
Typically half the weight of other makes
Eglass with Carbon Fibre reinforcing is Infused with high
strength Epoxy Resins for high strength and durability
No corrosion
Compact design gives significantly shorter installed
length than others
13www.q-spd.com31/12/2013
Less Fuel and Higher Speeds:
Use up to 20% less fuel
Up to +26% higher top speeds
at 30knots, typically 15% higher
at 40knots, typically 18% to 20% higher
over 50 knots, typically 20% to over 26% higher
Higher, more efficient cruise speeds
14www.q-spd.com31/12/2013
Better Steering and Manoeuvrability
Side-mounted rudders operate in “hard” undisturbed water flow at all times
Better straight line tracking
More responsive and predictable steering than trailing rudders or articulating drives
15www.q-spd.com31/12/2013
Exceptional Reverse
The clever composite housing design, along
with an advanced propeller design ensures the
propeller is biting into hard un-aerated water
immediately reverse is selected
16www.q-spd.com31/12/2013
Smooth and Quiet
Carefully designed propellers that “slice” the water surface so there is no slapping effect.
Exhaust is ported through the composite housing which ventilates the propeller at low speed
Exhaust noise is minimal even when without mufflers
17www.q-spd.com31/12/2013
Low, Low Maintenance
Composite housing will not corrode
All metal is marine grade stainless steel or bronze and all bonded to sacrificial anodes
All hydraulics and thrust bearings are inboard, protected from the harsh elements
Steering and Driveline easily maintained without need to lift the boat

Clever Housing Design
Propeller ventilates the instant of forward motion
Q-SPD always ventilates immediately – even with low closed swim
platforms.
Do not need vent grills in swim platform to ventilate propeller – the
drive housing instantly creates an air cavity above the propellers so the
propeller can pull all the air they need.
Will also operate perfectly in a closed transom pocket.
Accelerate Faster and Hold Lower Planing Speeds
23www.q-spd.com31/12/2013
Contoured Housing Designed to Enhance Reverse
Propellers get hard water to work in immediately
Deflects reverse thrust down and under the hull
No need for trim to reverse effectively
No need for severe transom angles
24www.q-spd.com31/12/2013
Twin Side-mounted Rudders
Operate in hard clean water flow
Superior steering control – predictable and concise
Excellent Straight line Tracking
Special Contured Rudder Profile
Enhances Rudders Steering efficiency
More reactive
25www.q-spd.com31/12/2013
Maximum Propeller Protection
Drive and rudders create an enclosure for propeller to operate in, thus maximizing protection of crew, passengers and property.
26www.q-spd.com31/12/2013
Typical Configuration Has integrated, water cooled, trust bearing Is supplied complete with Propeller and Flexible Constant Velocity Cardan
Shaft to connect drive to gearbox

Close Coupled SD-F (fixed) drive
with CV flexible shaft coupling
Q-spd S D-F
A solution of modular components that can be integrated into the vessels design to create an integrated Surface Drive system
Flexible integration and design options
Especially designed to suit larger vessels
No need for complex trim management systems
For pleasure and commercial vessels
Q-SPD engineers work closely with vessel designers
Integrated exhaust for propeller ventilation
29www.q-spd.com31/12/2013
Q-SPD recognises there are often specialisedrequirements for Commercial or Custom Applications
For example: Lower Speed application (Q-SPD does work with low speed boats)
Larger vessels
Extra heavy loads
Variable loads
Multi or mixed drive applications
Special design features (eg: lowering platforms or zero draft)
Can be based on either SD or MY type drives (or even mixed)
30www.q-spd.com31/12/2013
Q-SPD works designers to help develop there special driveline and installation needs – bringing concept to
reality.
