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

Figure B-11. Power level vs rotation ratio.
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.
TECH TIP
In many vessels, the Y-values will all be the same.
