thereby allowing use of the throttle without engaging the transmission. This is used for warm-up of the
engine while it is still in Neutral. Be sure to position the throttle vertically (in Neutral) before re-engaging the
transmission by depressing the knob.
When engaging the transmission from neutral either forward or backward into reverse, pull up on
the safety collar located directly below the throttle lever knob. The safety collar helps avoid unintentional
movement into gear.
When shifting gears, always do so smoothly and briskly. Being either too hard and slamming the gears,
or too tentative is hard on the shifter/throttle system and can result in damage that is not covered under
warranty.
Improper shifting and use of the throttle can result in damage
to the system that is not covered under warranty. The shifter/
throttle manufacturer has included additional instructions that
are part of the owner’s packet. Be sure to read and follow the
instructions and additional information to ensure long and safe operation of the boat.
Do not shift from forward to reverse while the engine is at high
RPM. Damage to the transmission will result. When shifting
from forward to reverse, the system requires a brief pause
in the Neutral position to allow the engine to run in its idle
position prior to moving into the opposite gear. Without this brief pause, it can also cause
the engine to shut OFF. The subsequent loss of control can cause damage to the boat and/
or injury to persons in or around the boat.
Before starting the engine or engaging the transmission, be
certain that there are no people in the water around the boat.
Models: All models.
Although unseen by the boat’s occupants, the Electronic Throttle Control (ETC) contributes to the
boat’s performance in critical fashion. Never make any modifications to the throttle control.
Never make any alternations or modifications to any part of
the throttle control system, including the throttle control. Such
changes render the engine and boat warranties void, and may
result in loss of control of the boat, which could result in serious
injury or death.
If, for any reason (unplugged, wire cut, a short, loss of power, or sensor failure, as examples), any part
of the electronic throttle control system fails, the engine controller will default to idle. The operator will
essentially have no control of the throttle and the Engine Fault alarm will activate.
If this happens, the operator must turn the ignition key to OFF, and then attempt to restart the engine.
This will reset the computer area network. If the condition persists, however, it will be necessary to take the
boat to an authorized Axis dealer for repair.
Additional information regarding the throttle control’s safe operation and maintenance is included in
additional separate material that is part of the new-boat informational package.
Models: All models.
