Trim Tab Adjustment
DUAL OUTBOARD
1. Check trim tab position as follows:
IMPORTANT: Initial trim tab setting for both out-
boards should be straight to rear of outboard, so
that tabs are aligned with gear housing center
line. Refer to “If Necessary, Adjust Trim Tab as
Follows,” following.
a. Operate boat at normal cruise throttle setting
and adjust trim to optimum setting.
b. If boat pulls to the right (starboard), trailing
edge of trim tab must be moved to the right
(when viewing outboard from behind). If boat
pulls to the left (port), trailing edge of trim tab
must be moved to the left.
2. If necessary, adjust trim tab as follows:
a. Shift outboard into neutral and make sure
ignition key is at “OFF” position.
b. Remove plastic cap from rear of drive shaft
housing and loosen bolt and trim tab.
IMPORTANT: Trim tabs MUST BE set in the same
position on both outboards.
c. If boat pulls to the right, adjust trailing edges
of both trim tabs to the right. If boat pulls to the
left, adjust trailing edges of both trim tabs to
the left.
d. Tighten both trim tab bolts securely and re-
place plastic caps.
e. Operate boat per “Check Trim Tab Position
as Follows,” preceding, to check trim tab set-
ting. Readjust trim tabs, if necessary.

1. Carefully check steering system components for
wear. Replace worn parts.
2. Check steering system fasteners to be sure that
they are torqued to correct specifications.
NOTE: Ride-Guide Steering cables are lubricated at
the factory and requires no additional lubrication at
initial installation.
WARNING
Core of each steering cable (transom end) must
be fully retracted into cable housing before lubri-
cating cable. If cable is lubricated while ex-
tended, hydraulic lock of cable could occur.
3. With core of Ride-Guide Steering cable (transom
end) fully retracted, lubricate transom end of
steering cable thru grease fittings (a) with 2-4-C
Marine Lubricant. Lubricate exposed portions of
cable ends (b) with 2-4-C Marine Lubricant.
4. Lubricate pivot points of steering link rods and
ball joints of link rods/steering coupler with Quick-
silver 2-4-C Lubricant.
5. Inspection and lubrication of steering head as-
sembly (rotary or straight rack) should be per-
formed once each year (by your Authorized Deal-
er) or whenever steering mount and/or steering
head are disassembled, or if steering effort has
increased. Lubricate with 2-4-C Marine Lubri-
cant.
