[. . . ] It is stopped by water resistance when the throttle lever is released. From full speed, the watercraft comes to a complete stop in approximately 90 m (300 ft) after the throttle is released and the engine is stopped, although this distance will vary depending on many factors, including gross weight, water surface conditions, and wind direction. The watercraft slows down as soon as the throttle lever is released, but will coast for a distance before fully stopping. If you are not sure you can stop in time before hitting an obstacle, apply throttle and turn in another direction. WARNING @ G G G G Allow adequate stopping distance. Remember, watercraft and other boats do not have brakes. Operate defensively at safe speeds and keep a safe distance away from people, objects, and other watercraft to give you time to stop. Do not shut the engine off when slowing down in case you need engine power to steer away from a boat or other obstacle that comes into your path. @ 3-29 E EJU01081 Beaching the watercraft 1. Make sure no obstructions, boats or swimmers are near the beach. Release the throttle lever about 90 m (300 ft) before you reach the intended beaching area. Approach the beach slowly and stop the engine before reaching land. Get off the watercraft and pull it up on the beach. CAUTION: @ Small pebbles, sand, seaweed, and other debris can be pulled into the jet intake and impair or damage the impeller. Allow the engine compartment to air dry completely before reinstalling the hood. 3-32 E EJU01297 Transporting WARNING @ Always place the fuel cock knob in the "OFF" position when transporting the watercraft, otherwise fuel could leak out into the engine or engine compartment, which would create a fire hazard. @ Transport this watercraft using the special trailer that incorporates a hole into which the pin 1 can be inserted and locked after passing it through the rope hole 2.
