1. If this is the initial tune, skip to step 3.
If you adjusted the power levels in STEP 8 and are now performing
a re-tune, adjust the X-values in the table as follows (see figure
B-12):
a) 1st = 0
b) 2nd = Normal Sideways Power from STEP 8
c) 3rd = Boost Sideways Power from STEP 8, minus 10%
d) 4th = 100
2. Write settings.
B.3.9 STEP 6 – Set Sideways Rudder Angle
When moving sideways we don't want the boat to rotate. We achieve
this by tuning the Power Level vs Rotation Ratio map. Perform in an
area with no wind or current to remove outside interference.
This step only adjusts for rotation during sideways movement. Fore/
aft movement during sideways movement will be adjusted in STEP 7.
3. Bring the boat to a complete stop with boost mode off.
4. Move the joystick sideways fully to port without rotating the knob.
a)
If the boat rotates clockwise as it starts to move, decrease both
normal mode Y-values (see figure B-12) by up to two units. If the
boat rotates counterclockwise, increase the values.
•
Note: The boat will rotate counterclockwise as it gains speed.
This is normal – our objective is to remove rotation during
initial movement.
b)
Write settings.
c) Repeat until the boat’s initial movement is directly sideways.
5. Repeat step 4 with boost mode enabled. This time adjust the boost
mode Y-values until there is no rotation during initial movement.
6. Write settings.
In many vessels, the Y-values will all be the same.
