A standard pre-starting procedure should be always be followed before the first start-up of the day.
1.Check the engine oil level.
2.Check for gasoline fumes in bilge or engine compartment.
3.Operate engine blower for 4 minutes before starting the engine to remove any fumes.
4.Check manual operation of bilge pump. Make sure bilge areas are empty.
Other items might also be inspected, depending on the boat and its use. It is advisable to formulate a check list
particular to the equipment and operation of your boat.
REFER TO THE BOATMAN’S CHECKLIST OF THIS MANUAL.
Consult the local Coast Guard Auxiliary or Power Squadron for full details on boating safety.
NOTE: Add-on electrical accessories should never be connected to the ignition terminal or ignition circuit.
IMPORTANT: DO NOT continue to operate the starter for more than 30 seconds at a time without pausing to
allow the starter motor to cool down for at least 2 minutes. This will also allow the battery to recover between
starting attempts. PLEASE REFER TO ENGINE OWNER’S MANUAL FOR ADDITIONAL DETAILS.
BEFORE STARTING ENGINE, BE SURE THAT THE SHIFT SELECTOR IS IN NEUTRAL.
The correct starting procedure depends upon the type of engine. Please refer to the engine manual before starting.
Do not start engine if gas fumes are present.
NOTE: Should the EFI engine become “flooded” use the
following procedure to start:
1. Place shift selector in Neutral and disengage the
transmission by pushing the transmission lockout button
located at the bottom of the lever.
2. With the transmission disengaged push the lever forward
to full throttle position. (This will cause the computer to
shut off the fuel injectors which will allow the engine to
clear of excess fuel during starting).
3. Turn the Ignition Key to Start Position and operate the
starter for no more than 15 seconds at a time until the
engine starts.
4. When the engine starts, back off the throttle and allow
the engine to establish a good idle (30 to 60 seconds).
5. Return the throttle to idle position and the transmission
lockout will automatically reengage the transmission in
neutral position.
6. When ready to get underway, shift slowly into forward
or reverse, allowing the transmission time to engage
the gearing before powering up.
NOTE: See also “EFI Phased Warm-Up”
To Start Electronic Fuel Injection
(EFI) Engine
1.Place shift selector in Neutral with the throttle in the upright
(zero) position. (If throttle is not in the idle position, the
throttle position sensor will not allow the engine computer
to proceed with a normal starting procedure).
2.Turn Ignition Key to Start Position to operate the starter.
3.Release the Key when engine starts (key will return to run
position).
4.Allow the engine to establish a good idle (30 to 60 seconds)
before getting underway.
5.Shift slowly into forward or reverse, allowing the
transmission time to engage before powering up.
NOTE: It is normal for the idle to speed up in cold start
conditions.
DO NOT continue to operate the starter for more than 30
seconds at a time without pausing to allow the starter
motor to cool down for at least 2 minutes. This will also
allow the battery to recover between starting attempts.
