7.3.5 Testing The Proportional Pause
A Position the boat in open water and slowly increase the Throttle to 25% of the speed range.
B Leave the Control Head lever(s) at this position for at least 60 seconds.
C Quickly move the Control Head lever(s) to Idle Astern.
• The engine(s) RPM should drop to Idle.
• The Clutch should stay engaged or shift to Neutral for 25% of the time selected with
Function Code C3 Proportional Pause Time.
• Once the time has expired, the Clutch should Shift to Astern.
• The engine RPM will drop slightly when the Astern load is placed on the engine, but not to
the point where it comes close to stalling.
D Increase the Throttle slightly until the vessel starts moving in the opposite direction.
• If the engine stalled or came very close to stalling, increase the Value of Function Code C3
by one second. Repeat steps A) through C).
• If the engine does not stall or come close to stalling, proceed with the next step.
E Repeat steps A) through D) with the Throttle at 50%, 75%, and 100% of the speed range.
• If the engine stalls at any time, increase the Value of Function Code C3 by one second and
repeat the steps A) through D) again.
F Once a Full Speed Reversal is successful without coming close to stalling, the Proportional
Pause is properly adjusted.
7.4 Synchronization Test (Twin Screw Only)
7.4.1 Equal Throttle Synchronization
A Move both Control Head levers side by side to approximately 25% of the Throttle range.
B If previously disabled, enable the synchronization by depressing the transfer button for two
seconds.
• The green LED on the Control Head should illuminate, indicating synchronization.
C Check the engine tachometers to see if they are within 1% of one another.
D Move both Control Head levers side by side to approximately 50% of the Throttle range.
E Check the engine tachometers to see if they are within 1% of one another.
F Move both Control Head levers side by side to approximately 75% of the Throttle range.
G Check the engine tachometers to see if they are within 1% of one another.
H Move both Control Head levers side by side to 100% of the Throttle range.
I Check the engine tachometers to see if they are within 1% of one another.
• While synchronized, if the tachometers have a greater than 1% difference at any engine
RPM, Active Synchronization is recommended.
7.4.2 Active Synchronization
A Move both Control Head levers side by side to approximately 25% of the Throttle range.
B If previously disabled, enable the synchronization by depressing the transfer button for two
seconds.
• The green LED on the Control Head may blink while driving toward synchronization.
• Once the engine RPM’s are within 1% of one another, the green LED will remain solidly lit.
C Check the engine tachometers to see if they are within 1% of one another.
D Move both Control Head levers side by side to approximately 50% of the Throttle range.
E Check the engine tachometers to see if they are within 1% of one another.
F Move both Control Head levers side by side to approximately 75% of the Throttle range.
G Check the engine tachometers to see if they are within 1% of one another.
CAUTION: It is critical that the Proportional Pause is tested as outlined below to ensure that it was properly
programmed. Failure to do so could cause damage to the transmission.
