1. Set Port
2. Set Starboard
3. Disable Calibration
Before calibrating the SECOND DPS outboard:
•
turn the key switch to the OFF position.
•
disconnect the battery cables at the battery for
the FIRST DPS outboard
•
connect the battery cables at the battery for the
SECOND DPS outboard
•
turn the key switch to the ON position
6. Repeat steps 1 through 5 for the SECOND
DPS outboard.
Connect the battery cables at the battery, then test
the steering system.
Steering System Test
Turn the steering wheel fully to PORT. The power
steering pump should run, then shut OFF when
the engine is turned fully to PORT.
Turn the steering wheel fully to STARBOARD.
The power steering pump should run, then shut
OFF when the engine is turned fully to STAR-
BOARD.
In some installations it may be difficult to hear the
power steering pump run. Use the Power Steering
screen of Evinrude Diagnostics software v 6.1 or
higher to monitor the pump Current and Duty
Cycle.
These values should be zero when the pump is
NOT running.

Propeller Selection

3
Selection of the wrong propeller could reduce
engine service life, affect boat performance,
1
or cause serious damage to the powerhead.
Water testing with various propeller designs and
2
sizes is the best method of propeller selection.
The correct propeller, under normal load condi-
tions, will allow the engine to run near the mid-
009400
point of the RPM operating range at full throttle.
Refer to SERVICE SPECIFICATIONS in the Ser-
vice Manual for RPM range.

If the propeller blades have too much pitch,
the engine will operate below its normal
range at full throttle. Power will be lost, and
powerhead damage could occur. If the propel-
ler blades have too little pitch, the engine will
operate above its normal range and damage
from overspeeding could occur.
When selecting a propeller, consider the following:
•
Use an accurate tachometer to determine the
engine's full-throttle RPM.
•
The outboard should be trimmed for top speed.
•
Select a propeller that suits the customer's
application and allows the engine to run near
the midpoint of the full-throttle operating range
when the boat has a normal load.
