I have a 1999 9.9 I recently purchased from an individual. It did not come with the owners manual. Does anyone know the fuel mixture for this year model and horse power?
Your mix should be the same as Spinner-bait Nut explains for the Merc, Mereect.<br /><br />One pint TCW-3 outboard oil to six gallons unleaded regular gas.<br /><br />Good luck.
