WHAT AND WHO IS Q-SPD?
• Q-SPD Surface Drives have been around since 2001 and have been developed and
refined over the years to become the reliable and user-friendly product it is today.
Q-SPD is a unique type of surface drive system that defies some of the common
idiosyncrasies of traditional surface drives and brings some modern thinking and
technologies into the design and application.
• Despite Q-SPD’s simple and clean appearance the innovative design puts all
vulnerable components inboard away from the elements. With less moving parts
there is naturally less to go wrong, guaranteeing reliability and longevity.
When we don’t hear from our customers, we know it’s a good thing.
• All this and still match performance expectations but with the ability to apply to a
more diverse range of applications, including low, medium and high-speed vessels.
• Q-SPD is an investment in your boat’s future – Less time on hard stands, more time
on the water.
Q-SPD is based
in
Auckland,
New Zealand

WHAT IS A SURFACE DRIVE?
• 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.
• A surface piercing 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.

WHAT MAKES Q-SPD MORE EFFICIENT?
 Appendage drag is reduced by more than 50%
 No prop shaft and skeg creating drag
 Only half the propeller is immersed so less drag
 Only a fraction of rudder is immersed at speed
 No entrained water to carry, as with Water Jets
 Surface propellers are ventilated – DO NOT CAVITATE
 No cavitation increases efficiency, propeller
 Larger more efficient propellers are possible
LOWER FUEL BURN ..… HIGHER SPEED .… SHALLOW DRAFT

Q-SPD’s MISSION
TO CAPITALISE ON:
 Our experience with surface drive technology
 Using intelligent design and innovation
TO CREATE AN ADVANCED PROPULSION SOLUTION THAT OFFERS:
 High performance and efficiency
 Lowest possible maintenance
THAT IS:
 100% Reliable and VERY user friendly
“THE Q-SPD ADVANTAGE”

THE Q-SPD ADVANTAGE
Special Housing Design
Automatically ventilates propellers for effortless acceleration.
Integral Thrust Bearing
Water cooled, oil lubricated thrust assembly in 316 Stainless Steel.
All located inboard.
Unique Twin Rudders
For predictable, responsive steering and superior tracking at all speeds.
Highest Quality Propellers
Superior propeller designs are manufactured to highest standards and accuracy.
Hi-Tech Composites
Lightweight and very strong, - 1/2 the weight of others.
Lowest Maintenance
Virtually zero maintenance needed year after year.
All Connections Inboard
Easy to service and stays clean.
Contoured Waterflow Design
For positive operation forward and reverse.

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

LESS FUEL AND HIGHER SPEEDS
• Up to + 20% less fuel
• Higher cruise and top speed
• at 30knots, typically 15% higher
• at 40knots, typically 18% to 20% higher
• over 50 knots, typically 20% to over 26% higher
• Higher and more efficient cruise speeds

Speed increases will be more where hull enhancements are included such as steps and/or foils.

BETTER STEERING AND MANOEUVRABILITY
Side-mounted rudders operating in “hard” undisturbed water flow at all times
• Better tracking at all speeds
• Responsive and predictable steering than trailing rudders or articulating drives
BETTER REVERSE
• The uniquely designed composite housing, along with advances in propeller design
ensures the propeller is biting into hard un-aerated water immediately reverse is
selected thus improving reverse performance.

SMOOTH AND QUIET
• Carefully designed propellers that “slice” the water surface so there is no
slapping effect.
• Exhaust is ported through the composite housing and ventilates the
propeller at low speed so no cavitation noise
• Exhaust noise is suppressed as it passes through the Q-SPD housing and
merges with the thrust from the propeller, thus additional mufflers not
needed.

LOWEST MAINTENANCE
• Composite housing is very strong and will not corrode
• All metal components are marine grade stainless steel or bronze and all
bonded to sacrificial anodes
• All hydraulics and thrust bearings are inboard, protected from the harsh
elements
• All immersed bearings and bushes are long life water lubricated type
• Over size thrust bearings are oil lubricated and water cooled for extended life
• Regular servicing in very minimal and easy
