no power

[walkingstick]

I have a mid 80s 60 horsepower Evinrude.. I rebuilt the carburetors on it and replaced the impeller at the same time.. now I'm no stranger to carburetors.. Especially these they are are extremely simple. But after the carburetor rebuild and replacing the impeller I have a problem.. the boat will not throttle up under power . It starts ...idles ... and runs fine at low speed but when you apply power it feels like I'm dragging an anchor ..it's simply won't power up... I get about 10 miles per hour out of it. In neutral it revs just fine. I have taken the carburetors apart again and found no apparent problems... any thoughts or ideas would be greatly appreciated

Might want to put this in the Johnson/Evinrude section, very knowledgeable guys in that section about these motors

Revving in neutral doesn't tell you anything.

When you move the throttle, does the timing link move? With motor off, shift into forward (turn prop by hand to let the shift dogs line up), then observe all the motion of the throttle lever. Does the roller on the throttle cam contact at the correct point? Do the carb plates then open fully?
