Checking Wiring And Connectors; Exhaust Leakage; Water Leakage; Checking Power Trim And - PowerTec 40Hp Owner's Manual

Maitenance
A diagnostic tachometer should be used for
this procedure. Results may vary depending
on whether testing is conducted with the
flushing attachment, in a test tank, or with the
outboard motor in the water.
1. Start the engine and allow it to warm up
fully in neutral until it is running smooth-
ly.
NOTE:
Correct idling speed inspection is only possi-
ble if the engine is fully warmed up. If not
warmed up fully, the idle speed will measure
higher than normal. If you have difficulty ver-
ifying the idle speed, or the idle speed re-
quires adjustment, consult a PowertecOut-
Boards dealer
or other qualified mechanic.
2.
Verify whether the idle speed is set to
specification. For idle speed specifica-
tions, see page 46.

Checking wiring and connectors

Check that each grounding wire is properly
secured.
Check that each connector is engaged se-
curely.

Exhaust leakage

Start the engine and check that no exhaust
leaks from the joints between the exhaust
cover, cylinder head, and body cylinder.

Water leakage

Start the engine and check that no water
leaks from the joints between the exhaust
cover, cylinder head, and body cylinder.
Checking power trim and tilt / power
tilt system
WARNING
Never get under the lower unit while it
is tilted, even when the tilt support lever
is locked. Severe injury could occur if
the outboard motor accidentally falls.
Make sure no one is under the outboard
motor before performing this test.
Check the power trim and tilt unit / the
power tilt unit for any sign of oil leaks.
1. Trim and tilt rod
2. Tilt support lever
Operate each of the power trim and tilt
switches / the power tilt switches on the
remote control and engine bottom cowl-
ing (if equipped) to check that all switch-
es work.
Tilt the outboard motor up and check
that the trim and tilt rod / the tilt rod is
pushed out completely.
Check that the trim and tilt rod / the tilt
rod is free of corrosion or other flaws.
Tilt the outboard motor down. Check
