Hey everybody today I got a 1971 9.5 evinrude that seems to slip out of gear when running at high Rpms. Once in foward gear the prop will spin fine until I hit about half throttle and the prop stops spinning but the lever is still engaged into foward same for reverse. Once I return to idle it starts spinning again. The interesting thing is that when I first start it up and put it into foward it runs fine. I can put it into neutral than back into foward and no issues unti I shift it into reverse and then once I put it back into foward gear this issues starts to occur. This engine had this issue before so I rebuilt the lower unit gears. Installed a new foward and reverse and clutch dog. Gear oil was fine once I drained it to make sure there were no leaks.
