Hi,<br />You did not write what model You have...<br />In the Owner's Manual for Your model it is a maintenance chart.<br />You can find all manuals for Yamaha outboards in PDF format at Yamaha US website.<br /><br /> http://www.yamaha-motor.com/products/categories02/5/otb/yamaha_outboard_motors.aspx <br />(Parts & Service, View Owner's Manual and select<br />2003, Outboard Motors and last Your model)<br /><br />I have a Yamaha outboard myself, F115 4-stroke (2003).
