Trim and Tilt Motor No Load Test
IMPORTANT: Securely fasten motor in a suit-
able fixture before proceeding with this test.
Use a battery rated at 360 CCA (50 Ah) or higher
that is in good condition and fully charged to per-
form this test.
Connect a 0 to 50 A ammeter in series with the
battery positive (+) terminal, ammeter red lead
toward battery.
Attach or hold a vibration or mechanical tachome-
ter to the motor while performing this test.
Monitor motor RPM and current draw.
The motor shaft must rotate clockwise, as viewed
from the pump end, when positive (+) is applied to
the blue lead, and negative (–) is connected to
green lead.
The motor shaft must rotate counterclockwise, as
viewed from the pump end, when positive (+) is
applied to the green lead, and negative (–) is
applied to the blue lead.
If test results vary, replace the motor.
Trim Gauge Test
STEP 1
Turn key switch ON. Using a voltmeter, check for
voltage between the trim gauge “I” and “G” termi-
nals.
• If no voltage, check condition of instrument har-
ness, key switch, and engine 20 A fuse.
• If voltage, go to STEP 2.
STEP 2
Remove the white/tan lead from the trim gauge
“S” terminal. With key switch ON, gauge should
indicate full-trim DOWN position. Now connect a
jumper wire between terminals “S” and “G.” Gauge
should indicate full-trim UP position.
• If results are different, replace the trim gauge.
• If results agree, refer to Trim Sender Test on
p. 292.
