b.3.10 Step 7 – balance Sideways engine power
In this step you will adjust the power ratio between the REV and FWD
engines to eliminate fore/aft movement when moving the boat sideways.
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-13):
a) 1st = 0
b) 2nd = Normal Sideways Power value from STEP 8 plus
5 units
c) 3rd = Normal Sideways Power value from STEP 8, minus 10%
d) 4th = 100
2. write settings.

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 moves aft, decrease both normal mode Y-values
(see figure B-13) 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 moves directly sideways.
5. Repeat step 4 with boost mode enabled. This time adjust the
boost mode Y-values until the boat moves directly sideways.
6. write settings.
tip: In many vessels, the Y-values will all be the same.
