F 200 4 stroke speedometer not working

can anyone out there help ? bought motor 2007
tried to blow out speed tube but didn't work

pickup tube in leading edge of lower unit is most likely clogged...you can use a small diameter drill bit by hand to try to clear debris.

Jb123,

Thanks For The Info I Will Try To Locate Tube Pickup Now That I Know Where It Is.
