Hi, My 70 Horse Evinrude Sounds Like It Runs Good When Its Not In The Water, But When In The Water It Wont Push Me More Than About Five Miles Per Hour... It Has Just Had Rebuilt Carbs By Myself, Maybe That Could Be A Problem??? But Why Would It Only Bog Down In The Water??? Primer Ball Stays Hard Too....
Please Help Me.

Why the carb rebuild, and did you check the compression first? Did you put the carb, and ignition linkage back in proper sync? Do you have a service manual?

Did you find the carbs gunky,did you soak them to remove all the gunk thats inside the passages you cant see,check to be sure the timer plate under the flywheel is rotating ,and properly,are you sure you have spart to ALL cylinders
