Checking the crank position sensor
air gap
1. Remove the wiring harness guide bolts
and uphold wiring harness guide.
2. Turn the flywheel magnet clockwise to

3. Measure the crank position sensor air
gap a. Adjust if out of specification.
Crank position sensor air gap a:
1.4–1.6 mm (0.055–0.063 in)
4. Loosen the screws 1 and adjust the
crank position sensor air gap.

5. Tighten the screws 1, and then check
the crank position sensor air gap. Adjust
again if out of specification.

4 N·m (0.4 kgf·m, 3.0 ft·lb)
Checking the intake air temperature
sensor
1. Measure the ambient temperature.
2. Connect a computer to the outboard
motor and use the YDIS to display the
intake air temperature.
