Bill,
The push-pull choke knob is also used to adjust the idle by turning it. It
is turned clockwise to increase engine speed and counterclockwise to
decrease it. Starting instructions suggest turning the choke knob fully
clockwise for starting and then decreasing engine speed as desired after it
is started by turning the choke knob counterclockwise. I feel my problem is
that with the knob fully clockwise, engine speed is still at an idle and not
significantly increased. I appreciate your response Bill.

If you look closer, I think you will find a push/pull knob for choking the
engine. Not the idle adjuster you are turning.

I recently purchased a boat with a 25 hp Mercury outboard. I am unsure
the
age of the oatboard but it looks to have been well taken care of. The
motor
is difficult to start when cold but starts very easily when warmed up.
The
motor has a choke knob which you can turn to increase the throttle
setting
while the engine is not in gear. Otherwise, when the tiller handle
"speed
control" is twisted one way or another to increase engine speed, the
propeller is automatically engaged. My situation is that when the choke
control knob is turned fully clockwise it hardly increases engine speed
at
all. Should turning the knob clockwise dramatically increase engine
speed
when the motor is in neutral? If so, I feel that is my problem with a
cold
start as the engine is at a low idle speed when attempting to start it.
How
can I make an adjustment to increase the starting engine speed? I
appreciate anyone's help that is familiar with this motor.
