Engine Break-In Period
Engine Break-In Period
New engines require a period of break-in to allow the surfaces of the moving parts to
mate evenly. Different engines require different break-in periods and methods. For
instructions on break-in methods, refer to your Yamaha Engine Owner’s Manual for the
correct break-in procedures and times for your model engine.
Engine Stop Switch
If activated, the spring-loaded engine stop switch will
automatically shut down the engine during emergency
situations to prevent uncontrolled or unattended
operation. Certain emergency conditions (e.g., turbulent
water, wakes, unanticipated movement) may impair a
person’s ability to operate the craft safely. The switch,
located on the helm, must have the safety lanyard
attached at its base. This activates the protective
shutdown circuitry.
Securely attach the other end of the lanyard to the operator of the boat. If the operator
moves, falls or is at an unsafe distance from the steering wheel, tension on the lanyard
will pull it from the switch. When the lanyard is removed, the engine stop switch is
released and automatic engine shutdown occurs.
Engine Stop Switch
DANGER:
An engine stop switch system that is not used or does not function
properly can cause death or serious injury. DO NOT operate the boat if
the engine stop switch system does not function properly. Go to a
Hewes Dealer to have this resolved immediately.
The lanyard should be securely attached to the boat operator at all times that
the engine is on.
