Yamaha 60hp timing belt

[bay slayer]

I have a 2003 60hp high thrust 4 stroke with 443 hours on it. I am wondering when I should change the timing belt? Thanks in advance for the help

reccomended intravel is 5 years or 1000 hours whichever occurs first.

I guess its time.Will a manual give me instruction on how to line up the timing marks?

yep
its simple.
line up the flywheel and cam marks and do it.
picture is in the book.
