5. Turn boost mode off on the joystick. Select off-Idle rev/fwd
ratio on the display and adjust the value so that it is the same
as the Normal REV/FWD Ratio parameter.
In many cases the off-idle rotation power balance will be adequate
at this point, but you may find the vessel drifts aft at small
joystick inputs, especially when the joystick is tuned with higher
peak power levels. You can improve the off-idle performance
with the optional step below.
6. Optional: Keep an eye on your port engine tachometer and slowly
rotate the joystick clockwise (CW) until the engine comes just off
idle. Hold the joystick at this point.
a. If the boat moves aft, decrease the Off-Idle REV/FWD Ratio.
b. If the boat moves forward, try rotating the joystick a little
more. If the boat still doesn't move aft there is no adjustment
to make. Leave the Off-Idle REV/FWD Ratio the same as the
Normal REV/FWD Ratio. It should never be higher.
c. Press Save.
d. Repeat until the boat rotates on the spot with no fore/aft
movement.
9.2.6 Step 6 – Set Sideways rudder angle
When moving sideways we don't want the boat to rotate. We achieve
this by tuning the Sideways Rudder Angle parameters. For best results,
perform in an area with as little wind and current as possible.
This step only adjusts for rotation during sideways movement. Fore/
aft movement during sideways motion will be adjusted in STEP 7.
1. Bring the boat to a stop with boost mode off.
2. On the display, navigate to dealer menu > Initial Setup > joystick
> Set Sideways rudder angle. Select normal rudder angle. The
default parameter values may be different on your installation.
