If changing conditions cause the RPM to drop below the recommended range, such as warmer, more humid
weather, operation at higher elevations, increased boat load, or a dirty boat bottom/gearcase, a propeller change
or cleaning may be required to maintain performance and ensure the outboards durability.
Check full-throttle RPM, using an accurate tachometer, with the engine trimmed out to a balanced-steering
condition (steering effort equal in both directions) without causing the propeller to break loose.
Lanyard Stop Switch
The purpose of a lanyard stop switch is to turn off the engine when the operator moves far enough away from
the operator's position (as in accidental ejection from the operator's position) to activate the switch. Tiller handle
outboards and some remote control units are equipped with a lanyard stop switch. A lanyard stop switch can be
installed as an accessory - generally on the dashboard or side adjacent to the operator's position.
The lanyard is a cord usually between 122 and 152 cm (4 and 5 feet) in length when stretched out, with an
element on one end made to be inserted into the switch and a snap on the other end for attaching to the operator.
The lanyard is coiled to make its at-rest condition as short as possible to minimize the likelihood of lanyard
entanglement with nearby objects. Its stretched-out length is made to minimize the likelihood of accidental
activation should the operator choose to move around in an area close to the normal operator's position. If it is
desired to have a shorter lanyard, wrap the lanyard around the operator's wrist or leg, or tie a knot in the lanyard.

Read the following Safety Information before proceeding.
Important Safety Information: The purpose of a lanyard stop switch is to stop the engine when the operator
moves far enough away from the operator's position to activate the switch. This would occur if the operator
accidentally falls overboard or moves within the boat a sufficient distance from the operator's position. Falling
overboard and accidental ejections are more likely to occur in certain types of boats such as low sided inflatables,
bass boats, high performance boats, and light, sensitive handling fishing boats operated by a hand tiller. Falling
overboard and accidental ejections are also likely to occur as a result of poor operating practices such as sitting
on the back of the seat or gunwale at planing speeds, standing at planing speeds, sitting on elevated fishing
boat decks, operating at planing speeds in shallow or obstacle infested waters, releasing your grip on a steering
wheel or tiller handle that is pulling in one direction, drinking alcohol or consuming drugs, or daring high speed
boat maneuvers.
While activation of the lanyard stop switch will stop the engine immediately, a boat will continue to coast for some
distance depending upon the velocity and degree of any turn at shut down. However, the boat will not complete
a full circle. While the boat is coasting, it can cause injury to anyone in the boat's path as seriously as the boat
would when under power.
