Pre-operation checks
Before operating the Helm Master control system, perform the following check. Make sure to
turn the ignition switch ON when performing the check.
WARNING
Do not operate the boat if any Helm Master control system component does not func-
tion properly.
Item Actions
Hydraulic fluid level
• Check the hydraulic fluid level. See page 36.
• Check whether the level of fluid in the steering pump reser-
voir moves up or down when the steering wheel is being
turned. Fluctuating fluid level indicates possible air
entrapped in the hydraulic system. Contact a Yamaha
dealer.
Hydraulic fluid leakage
• Inspect hydraulic hose and connections.
• Turn steering wheel fully in one direction and then an addi-
tional 1/2 turn, and then inspect the connecting section
between the steering pump and power steering cylinder.
Also perform checks with the steering wheel turned in the
opposite direction.
• Check the hydraulic fluid hoses and connecting sections
for wear, twisting, and leaks.
• If there is fluid leakage, it must be repaired before operat-
ing the boat.
Steering bypass valve
• Check that the steering bypass valve is closed. See page
36.
Electrical component
• Check that the EKS switch active indicators are illuminated
when the ignition switches are turned ON.
• Check that the remote control active indicators are illumi-
nated when the ignition switches are turned ON.
• Place the EKS fob over the lock indicator to check that the
EKS panel lock indicator blinks.
Controls
• Turn the steering wheel fully left and fully right. Check that
all operating parts function smoothly without any catching
or excessive play. Check that the steering responds
instantly when the steering wheel is being turned.
• Check the steering control system components for binding,
excessive play, wear, and fluid leaks.
