                                     Engine break-in
                            ECJ00432

                            Failure to perform the engine break-in
                            could result in reduced engine life or even
                            severe engine damage.
                            The engine break-in is essential to allow the
                            various components of the engine to  wear
                            and polish themselves to the correct operat-
                            ing clearances. This ensures proper perfor-
                            mance and promotes longer component life.
                            To perform the engine break-in:
                            (1) Check the engine oil level. (See page 61
                                for information on checking  the  engine
                                oil level.)
                            (2) Launch the watercraft and start the en-
                                gine. (See page 76 for information  on
                                starting the engine.)
                            (3) For the first 5 minutes, operate with the
                                engine speed at 2000 r/min.
                            (4) For the next 30 minutes, operate with the
                                engine speed below 5000 r/min.
                            (5) For the next 1 hour, operate with the en-
                                gine speed below 6000 r/min.
                            After the engine break-in is complete, the wa-
                            tercraft can be operated normally.

                                                                                                   65
