Starting The Engine (Continued)
NOTE: It is not necessary to use the neutral fast idle speed feature
on the remote control to increase engine speed for starting and
warm up. The electronic starting system will automatically increase
idle speed for starting and will reduce it as the engine warms up.The
engine does not require you to actuate the primer (choke) for start-
ing. The electronic starting system will automatically prime the en-
gine.

Turn the ignition key to START position. Release the key when
engine starts. If engine fails to start in 10 seconds, return the key
to ON position, wait 30 seconds and try again.
NOTE: Starting Flooded Engine – Advance the neutral high idle
speed feature on the remote control to the full high speed position.
Crank engine for 10 seconds, wait 30 seconds and repeat until en-
gine starts.

Check for a steady stream of water flowing out of the water pump
indicator hole (allow approximately 10-15 seconds for the water
flow to start).
IMPORTANT: If no water is coming out of the water pump indi-
cator hole, stop engine and check cooling water intake holes
for obstruction. No obstruction may indicate a water pump fail-
ure or blockage in the cooling system. These conditions will
cause the engine to overheat. Have the outboard checked by
your dealer. Operating the engine while overheated will cause
engine damage.
