I have about a 6 year old Evinrude 48 SPL that has a problem. It idles fine
and revs fine as long as it is not in gear but once you put it in gear
there is no power and it is hard to keep it running. I checked the foot for
gear lube and it seems fine. Put a water clamp on it and ran it in my
driveway and the prop turns freely. Rotated the prop by hand with the engine
off and it spins freely. Does anyone have any ideas?

Thanks for your input.
