520 Stern Drive Description
The Konrad 520 stern drive is the hardest working stern
drive in the marine industry today. Designed for high-
use, endurance-type applications, the Konrad 520 is
recognized for its versatility and long-term durability.
It is not a “pleasure” drive. It’s a working drive that
can take you shing all day or patrol harbors 24/7. The
Konrad 520 is the only commercial-rated stern drive
available for diesel applications in the 180-440 hp
(134 - 328 kw) range.
The Konrad 520 stern drive is designed to
accommodate aluminum or stainless steel propellers
with three (3) to ve (5) blades. Propellers are chosen
depending on the application and performance criteria.
The maximum diameter propeller size for the Konrad
520 stern drive is 20 in. (50.8 cm).
500 SERIES INSTALLATION MANUALJULY 2016 PAGE 1

The Konrad 540 is specically designed for high speed
applications, both diesel and gasoline. This versatile
stern drive is manufactured in two variations: Standard
and High Performance. The High Performance model
includes a lower hydrodynamic nose cone, and both
versions have a lightweight design to deliver superior
hole-shot and on-plane performance. The Konrad 540
allows mariners to apply greater power levels, while
still delivering performance and reliability.
The Konrad 540 stern drive is designed to
accommodate aluminum or stainless steel propellers
with three (3) to six (6) blades. Propellers are chosen
depending on the application and performance criteria.
The maximum diameter propeller size for the Konrad
540 stern drive is 16 in. (40.6 cm).
Commercial Performance
Maximum recommendation:
755 Nm (557 lb. ft.) of torque for diesel
or gas applications. Maximum operation:
500 hours per year for planing type
hulls of highly intermittent operation.
Gross weight to horsepower less than
12.2 kg/kw (20 lbs./hp). This clas-
sication includes light commercial
charter/sport activity craft, patrol and
intercept boats. Standard warranty.
High Performance
Maximum operation:
100 hours/year for racing applications at
highly intermittent operation. Gross weight
to horsepower less than 12.2 kg/kw (20
lbs./hp). No warranty.

The Konrad 560 Twin Prop System is engineered
to reduce stress on the gears using dual propeller
technology, providing a reliable, durable stern drive
unit. With counter rotating propellers, the 560 reduces
propeller roll, which increases efciency and control.
The Konrad 560 stern drive features two, one
piece propeller shafts that accommodate two
stainless steel propellers. The specially designed
propellers have one blade conguration: 3 blades
on the forward prop and 4 blades on the rear
prop. The propeller pitches are manipulated on
each application to meet the performance criteria.
The maximum diameter of the propellers in the
Konrad 560 is 16 in. (40.6 cm) for the forward
prop, and 15.25 in. (38.7 cm) for the rear prop.

Stern Drive
General Information
The Konrad 500 Series stern drives are designed
to accommodate engines that generate up to 738 lb.
ft. (1000 Nm) of torque.
There is a sixteen degree (16°) trim range to
optimize vessel performance while underway.
There is an additional 30 degrees (30°) of lift range
that may only be used in an emergency or when the
stern drive is being serviced or transported.
The Konrad 500 Series stern drives are
designed for applications where the vessel transom
angle is 14 degrees (14°). Applications that do not
meet this criteria may require extra equipment or
modications, or may not be possible at all. The
Konrad 520 stern drive is designed to accommodate
propellers (aluminum and stainless steel) with
a maximum diameter of 20 in (50.8 cm). The
Konrad 540 and 560 can accommodate propellers
(aluminum and stainless steel) with a maximum
diameter of 16 in. (40.6 cm).
General Operation
The engine produces power (clockwise or
counterclockwise) that is transmitted through a
reversing transmission. A coaxial planetary-style
reversing transmission is normally used in recre-
ational applications. A twin shaft vertically offset
standard reversing transmission (with coaxial ad-
ditions available) is normally used in commercial
applications. From this point the transmission is
connected via close couple or drive shaft (different
shafts are discussed in detail in Step 6 on pages 29
- 32 in this manual). The power is then transmitted
through a series of shafts and gears and then to the
propeller(s).
Safety Notices
Read and understand all of the safety precau-
tions and warnings before performing any installa-
tion or repair.
This list contains the general safety precautions
and warnings that MUST be followed to provide
personal safety. This list is only a suggested safety
guideline. Working conditions vary greatly and
safety measures will vary upon your individual cir-
cumstances.
ALWAYS USE CAUTION. Make sure the
work area surrounding the product is safe. Be
aware of hazardous conditions that can exist.
ALWAYS wear protective eyewear and
protective footwear when working.
DO NOT wear loose-tting or torn clothing.
Remove all jewelry when working.
DO NOT work on anything that is supported
only by lifting jacks or a hoist.
ALWAYS use blocks or proper stands to
support the product before performing any
service work.
TO AVOID PERSONAL INJURY, use
a hoist or get assistance when lifting stern
drive components. Make sure all lifting de-
vices such as chains, hooks or slings are in
good condition and are of the correct lifting
capacity.
