Engine stop lanyard switch
The lock-plate on the end of the lanyard must be attached to the engine stop switch for the engine to run. The lanyard should be attached to a secure place on the operator’s clothing, or arm or leg.
Should the operator fall overboard or leave the helm, the lanyard will pull out the lock plate, stopping ignition to the engine. This will prevent the boat from running away under power.
w
8 Attach the engine stop switch lanyard to a secure place on your clothing, your arm or leg while operating.
8 Do not attach the lanyard to clothing that could tear loose. Do not route the lanyard in such a way that it could become entangled, preventing it from functioning.
8 Avoid accidentally pulling the lanyard during normal operation. Loss of engine power means the loss of most steering control. Also, without engine power, the boat could slow rapidly.
This could cause people and objects in the boat to be thrown forward.
NOTE:
The engine cannot be started with the lock-plate removed.

POWER TRIM/TILT SWITCH
The power trim/tilt adjusts the motor angle in relation to the transom. The power trim/tilt switch is located on the side of the bottom engine cowling. Pushing the switch “UP” trims the motor up, then tilts the motor up. Pressing the switch “DN” tilts the motor down and trims the motor down. When the switch button is released, the motor will stop in its current position.
w
Use the power trim/tilt switch located on the bottom engine cowling only when the boat is at a complete stop with the engine off. Attempting to use the cowling-mounted power trim/tilt switch while the boat is moving could increase the risk of falling overboard and could distract the operator, increasing the risk of collision with another boat or an obstacle.
NOTE:
Refer to the section “Adjusting Trim
Angle” and “Tilting Up/Down” for instructions on usage.
