Three Piston System - BRP EVINRUDE E-TEC 115 HP 2011 Service Manual

TRIM AND TILT
TROUBLESHOOTING

Three Piston System

If the power trim/tilt system has malfunctioned and
the cause has not been determined, the Symp-
toms Chart on p. 336 should help locate the
problem.
Keep a manual release valve and a valve body in
stock for troubleshooting. Use these parts when
the Service Procedures on p. 336 call for the
substitution of known good parts.
If the trim/tilt does not work, and its motor neither
runs nor hums, troubleshoot the problem by refer-
ring to TILT/TRIM RELAY TEST on p. 104.
If the outboard tilts part way up but not smoothly,
or with a constant sound, there is probably air in
the system due to low fluid. Fill reservoir and
bleed (purge air from) the system.
To test for mechanical binding, open the manual
release valve and manually tilt the motor up and
down. If parts are binding, refer to MIDSECTION
section.
If a V4 model will not lower from shallow water
drive position at any throttle setting, or if a V6
model will not stay in shallow water drive and
drops down at fast idle, the wrong manual release
valve may be installed. Check for the identification
groove in the face of the valve.

If the outboard does not tilt as high as it should,
and the tilt motor TURNS OFF at maximum tilt
(does not sound like it is stalled at the maximum
tilt position), adjust the tilt limit switch higher and
retest. Refer to Tilt Limit Switch Adjustment on
p. 27.

Service Procedures
STEP 1
Be sure the manual release valve is closed. If
NOT, torque to 45 to 55 in. lbs. (5 to 6 N·m).
STEP 2
Temporarily install a known good manual release
valve and retest. If symptoms remain, original
valve is not the problem. Reinstall original valve.

If symptoms disappear, the original valve was
faulty. Remove temporary valve and replace with
correct new valve.
