Rotary Valve Timing

Does anyone have the numbers for a 99 mxz 500? I am putting it back together for a guy and his case has 2 scribed lines and a notch on the case. The 2 scribed lines are about 5 degrees and 7 degrees counter clockwise of the notch on the case. I alwasys used to use the notch on the case for a sea doo. I am thinking it needs to end up between the 2 scribed lines on this motor but I'd like to be sure.

Thanks
