NOTE:Refer to the following notes:
1. Lowering the pitch of the propeller will increase the engine speed above
the 5,800 RPM lower threshold, to account for variations in loading and
ambient conditions.
2. Increasing the pitch of the propeller will decrease the engine speed below
the 6,400 RPM upper threshold, to account for variations in loading and
ambient conditions.
3. Demand may be slightly less than 100%.
Adaptive Speed Control Propping without CDS G3
IMPORTANT:Boat propping can be performed using the normal method used
for Mercury Outboards. To achieve optimum propeller selection, however,
follow the Adaptive Speed Control Propping with CDS G3 procedure.
IMPORTANT:To operate the engine at full throttle before the break‑in period is
complete, follow this procedure.
1. Place the remote control in neutral, idle speed and start the engine.
2. Slowly advance the throttle until the engine reaches 1300 RPM (± 100
RPM).
3. Watch all gauges for normal readings.
4. When the engine reaches normal operating temperature, run the boat up
on plane.
5. Advance the engine RPM (in 200 RPM increments) until the engine
reaches its maximum rated RPM. Refer to the following table for the
wide‑open throttle RPM range.
