Features and functions

When the engine is running, cooling water is circulated in the engine, and then it is discharged from the pilot outlets.

To check for proper operation of the cooling system, check that water is being discharged from the port (left) pilot outlets. If water is not being discharged from these outlets, cooling water may not be circulating in the engine. When this occurs, stop the engine and check for the cause. (See pages 51 and 106 for more information.)

NOTE:

●If the cooling water passages are dry, it will take about 60 seconds for the water to reach the outlets after the engine is started.

●Water discharge may not be constant at idle, therefore, open the throttle a little to check that water discharges properly.

Steering system

Your watercraft can be steered by turning the handlebars in the direction you wish to travel.

1Handlebar

2Jet thrust nozzle

When the handlebars are turned, the angle of the jet thrust nozzle is changed, and the direction of the watercraft is changed accordingly. Since the strength of the jet thrust determines the speed and degree of a turn, throttle must always be applied when attempting a turn, except at trolling speed.

This model is equipped with the Yamaha Engine Management System (YEMS) that includes an off-throttle steering (OTS) system. It will activate at planing speeds should you attempt to steer the watercraft after releasing the throttle lever. The OTS system assists in turning by continuing to supply some thrust while the watercraft is decelerating, but you can turn more sharply if you apply throttle while turning the handlebars.

The OTS system does not function below planing speeds or when the engine is off.
