600B SERIES MAINTENANCE MANUALJULY 2016 - V1.0 PAGE 1
General Information
The Konrad 600B Series sterndrives are designed to accommodate engines that generate up to 1200 Nm
(885 lb. ft.) of torque at rated / maximum RPM. Maximum torque ratings are drive model and application
dependent.
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 sterndrive is
being serviced or transported.
The Konrad 600B Series sterndrives are designed for applications where the vessel transom angle is 13
degrees (13°). Applications that do not meet this criteria may require extra equipment or modications,
or may not be possible at all. The Konrad 620B and 680B sterndrives are designed to accommodate
propellers (aluminum or stainless steel) with a maximum diameter of 20 in (50.8 cm). The Konrad 660B
can accommodate propellers (stainless steel) with a maximum diameter of 16 in. (40.6 cm).
Safety Notices
Read and understand all of the safety precautions and warnings before performing any installation 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, consequently safety
measures will vary upon your individual circumstances. Always use caution. Make sure the work area
surrounding the product is safe. Be aware of hazardous conditions that can exist.
ALWAYS wear protective eyeglasses 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 drive components. Make
sure all lifting devices such as chains, hooks, or slings are in good condition and are of the correct
capacity.
ALWAYS use tools that are in good condition. Make sure you understand how to use them before doing
any service work.
ALWAYS use the same fastener part number (or equivalent) when replacing fasteners.
DO NOT use a fastener of lesser quality if replacements are necessary.
ADDITIONAL SAFETY PRECAUTIONS ARE INCLUDED IN THE PROCEDURES WHEN
APPLICABLE.
Chapter 1 - Sterndrive

600B SERIES MAINTENANCE MANUAL JULY 2016 - V1.0

Operation
The engine produces power (clockwise or counterclockwise) that is transmitted through a reversing
transmission. Either a coaxial planetary-style reversing transmission or a twin shaft vertically offset
standard reversing transmission (with coaxial additions available) are normally used depending upon your
application, and vessel design. The transmission is connected via close couple or drive shaft. The power is
then transmitted through a series of shafts and gears and then to the propeller(s).
WARNING: If a u-joint style drive shaft is used, the drive shaft angle may not exceed one-half
degree (.5º). If the angle exceeds one-half degree (.5º), any warranty offered with your application
is void.
Break-In Procedure
Make sure the sterndrive and gimbal carrier are properly lled with gear oil prior to operation.
Any new Konrad sterndrive unit, whether a lower, upper or complete, requires a ten (10) hour break-in
running period. Please use the following guidelines during the rst ten (10) hours to assure optimum
performance from your new Konrad sterndrive.
1. Avoid full throttle starts.
2. Avoid straining or heavy loading of the sterndrive.
3. To achieve even wear patterns on your new drive gear sets, operate at intermittent throttle
levels throughout the entire break-in period.
4. DO NOT exceed seventy-ve percent (75%) of full throttle during the rst ve (5) hours.
5. During the next ve (5) hours of the break-in period, operate periodically at full throttle.
6. The sterndrive should be shifted into forward gear a minimum of ten (10) times during
the rst ten (10) hours with moderate (but not excessive) RPM’s after each shift.
7. Change or lter (Using Konrad lter kit 13-389) the gear oil when the break-in period is
complete.
NOTE: When the initial oil change is done, small metal particles may be found in the break-in oil. Do
not be alarmed. This is typical during break-in and will decrease as you run the drive.
