Hey, yasefue. The usual suspects in this type problem:<br />1. Fuel starvation. If pumping your ball pump makes it go, this is your problem. Fuel pump failing or some restriction in the lines,tank or pickup.<br /><br />2. Linkage between throttle and ignition timing failing to advance timing.<br /><br />Good luck.<br />JB

Yasefue,<br /><br />I had the exact same problem with my 1970 85HP Evinrude when I first got it. would idle great and putt around no problem but when giving it full throttle it wouldn't even get on plane! I cleaned and rebuilt both carburetors. The next time I took it out I punched the throttle and got thrown into my seat!! Definitely get a rebuilt kit for your carb or carbs and clean them up.<br /><br />Joe

My Merc 1150 did the same thing. It was running to lean, had it set richer, has not been a problem in 2 + years now.
