b.3.8 Step 5 – balance rotation power
In this step you will tune the power ratio between the FWD and REV
engines to yield tight circles in rotation (ROT) mode. Perform in an
area with no wind or current to remove outside interference.
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-11):
a) 1st = 0
b) 2nd = Normal Rotation Power from STEP 8
c) 3rd = Boost Rotation Power from STEP 8, minus 10%
d) 4th = 100
2. write settings.

3. Bring the boat to a complete stop with boost mode off.
4. Rotate the joystick clockwise (CW).
a) If the boat moves aft while rotating, decrease both normal
mode Y-values (see figure B-11) by the same amount. If the boat
moves forward, increase the values.
• To start, adjust in increments of up to 50 units. Decrease the
increment size as the fore/aft movement is reduced.
b) write settings.
c) Repeat until the boat rotates on the spot with no fore/aft
movement.
5. Press boost on the joystick to enable boost mode, then repeat
step 4. This time, adjust the boost mode Y-values until fore/aft
movement is eliminated while rotating.
6. write settings.
tip: In many vessels, the Y-values will all be the same.
