DIAGNOSTIC
PROCEDURES
The key to effective troubleshooting is confirming
the proper operation of each engine system.
Causes of electrical failures may be difficult to iso-
late. Check the integrity of all connections,
grounds, and wiring prior to replacing a suspect
component. Refer to
GROUND CIRCUITS
on
p. 106.
Observe and run the outboard prior to performing
any unnecessary procedures. Initial inspection
should include the following:
•
Observe the outboard and confirm the actual
symptoms. Refer to
TROUBLE CHECK
CHART
at the end of this manual.
•
Inspect spark plugs for indication of wear, oil
fowling, or damage. A rich or lean running con-
dition or evidence of internal engine damage
could be identified by the appearance of the
spark plugs.
•
Make sure the outboard can be turned over
easily. There should not be any mechanical
binding.
•
Check the
