POWER TRIM SYSTEM /
STEERING HELM AND CABLE
Control System
Use the appropriate control panel or in-handle trim
control arrangement (for instance Teleflex controls)
with the power trim system. Install the trim control
according to the instructions included with the
power trim system.
Pump Location
Select a mounting location for the trim pump that
meets the following requirements:
• Within a comfortable reach of the hydraulic hoses
(coming from the gimbal housing assembly).
• Close enough to the battery so trim pump battery
leads can be connected.
• Allows easy access to the trim pump oil fill and
vent locations.
• In an area where the pump will not be exposed to
water.
• Mount the trim pump so that when the steering
wheel is turned either to the right or left the power
assist steering cylinder does not come in contact
with trim pump.
Steering Helm and Cable
The stern drive is shipped with the steering cable
guide preset for cables with end dimensions that
comply with ABYC standards, as outlined in the
NMMA certification handbook. Yanmar
recommends using the steering cable with a
coupler nut. There must also be a means of locking
it to the guide tube as specified in the ABYC
requirements.
WARNING!
Failure to use a steering cable
locking device could cause a loss of steering.
Yanmar recommends using the steering cable with
a self-locking coupler nut.
Use an external locking device if using a steering
cable that does not have a self-locking coupler nut.
Steering Cable Specifications
WARNING!
Power steering units only - If the
steering cable is installed with improper
dimensions, it may cause severe damage to the
transom assembly and / or steering system.
NEVER attempt to adjust the cable guide tube
on the power steering unit, as the guide tube
and locknut have been torqued (with Loctite®)
at the factory, and an attempt to loosen nut or
tube may result in damage to tube.
Ensure that the steering cable is the correct length,
particularly when installed in larger boats.
Route the cable so it does not go around any sharp
bends. Remove and avoid any kinks or loops, when
mounting the cable.
Use the following illustration to determine the cable
end dimension when the power steering cable is
fully-extended.
NOTICE: Power steering pump lugging (squealing)
in a hard right turn (against the lock) may mean that
the steering cable has been installed using
incorrect dimensions.
