To Start Your 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 15
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.

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.
Engine Warm-Up
Always let engine warm up to normal operating temperature
before accelerating.
