YNCHRONIZATION

The Mathers
®
gearshift and throttle control system
offers the option of automatic engine
synchronization.
When the engine synchronizers are in operation,
any engine speed differential is immediately sensed
and automatically corrected. A single throttle
movement is all that is necessary to ensure that
both engines maintain identical RPM.
The system allows the operator the option to disable
automatic engine synchronization while in
synchronization mode.

• depress the station transfer button (See
figure 3.7.1) for one second when the
Control Head levers are above 10 percent
throttle.TO RE-ENABLE:
• Match the Control Head levers above 10
percent throttle in FORWARD, and then
depress the station transfer button for one
second. Automatic synchronization is again
available, and Synchronization Mode is
active.

The optional integrated trolling valve control provides
controlled slow speed operation and enhances
operator control during docking maneuvers. A
selector switch at the Mathers
®
control station allows
the operator to select TROLL or NON-TROLL.
When TROLL is selected, the system commands
clutch direction, engine speed and trolling valve
position.
NOTE: Refer to your engine Owner’s Manual to
operate the throttle arm by hand for maintenance.

EATURE
:
• Select TROLL on the Control Head Position
the throttle and gear levers in the idle ahead
detent or idle astern detent:- Clutch
engagement commanded.
- Throttle limited to idle RPM.
- Trolling valve commanded to
minimum clutch oil pressure.
- Propeller shaft turning at minimum
RPM
• Move the control lever(s) from the
detent through the next 20 degrees:- Trolling
valve adjusts to increase clutch oil pressure
to increase shaft speed.
- Throttle limited to idle speed.
• Move the control lever(s) past 20 degrees.-
Trolling valve positioned to the maximum
clutch oil pressure.
- Engine speed increased in
proportion to the control lever(s)
position.
Moving the control head lever(s) back to neutral
will reverse the sequence. Operation in astern is
the same as ahead. See Section 2 - Major Controls
for additional operational information. See
Operational reference card in your owners packet
for specific details.
