Power Steering Wiring
The electronic power steering is an on demand
system using minimal power. The system uses two
60 amp breakers (one per starting battery) located
near the battery source. The breakers are between
each battery (twins) and the PCM mounting board.
The illustration below shows a typical twin engine
steering setup.
Hydraulic Steering Pump
Located in the Lazerrete com-
partment is the steering system
hydraulic pump system. Each
pump controls the port or star-
board steering cylinder. The Ya-
maha hydraulic steering system
uses HA5482 EPS power steering fluidl. Do not
use any substitutions. It is a good idea to have ex-
tra fluid, funnel and cloth on board for emergency
filling of the system. Also, note that there is a ser-
vice valve located on each pump. It allows for man-
ual realignment of the engines during service or a
system fault. Use the decal information as needed
for manual realignment situations. Engine(s) must
not be running while performing these realignment
procedures.
