User manual YAMAHA GP800-1999

[. . . ] If you have any questions about the operation or maintenance of your watercraft, please consult a Yamaha dealer. Because Yamaha has a policy of continuing product improvement, this product may not be exactly as described in this Owner's/ Operator's Manual. Specifications are subject to change without notice. This manual should be considered a permanent part of this watercraft and should remain with it even if the watercraft is subsequently sold. Important manual information: In this manual, information of particular importance is distinguished in the following ways: The Safety Alert Symbol means ATTENTION! [. . . ] Water sucked in through the intake grate is pressurized by the impeller in the jet pump. As the pressurized water is expelled from the pump through the jet thrust nozzle, it creates thrust to move and steer the watercraft. The higher the engine speed, the more thrust is produced. The amount of jet thrust, in addition to the position of the handlebars, determines how sharply you turn. More throttle produces higher thrust, so the watercraft will turn more sharply. Less throttle produces lower thrust, so the watercraft will turn more gradually. Releasing the throttle completely produces only minimum thrust. If you are traveling at speeds above trolling, you will have rapidly decreasing ability to steer without throttle. You may still have some turning ability immediately after releasing the throttle, but once the engine slows down, the watercraft will no longer respond to handlebar input until you apply throttle again or you reach a trolling speed. At trolling speed, the watercraft can be turned gradually by handlebar position alone using just the amount of thrust available at idle. If the engine is stopped while riding, there is no thrust. Operating in rough water or jumping waves can also crack the watercraft body or damage internal parts. Avoid operating in rough water or bad weather conditions. 3-30 E EJU00691a Post-operation checks Always perform the following post-operation checks after operating the watercraft. Wash down the hull, handlebars, and jet unit with fresh water. Remove the seat and check the engine compartment for water. To drain excess water, remove the stern drain plugs, then raise the bow of the watercraft enough to allow water in the bilge to drain out. NOTE: This watercraft is equipped with an automatic bilge-draining system that removes water from the engine compartment while you are underway. However, some residual water will remain. Put the watercraft in a horizontal position. Flush the cooling system to prevent it from clogging with salt, sand, or dirt. (See page 4-1 for flushing the cooling system procedures. ) 6.
