'88 OMC 5.0L Cobra not enough water at the impeller

[danieldi]

When i'm rising the stern and then lowering back in the water, the impeller is not getting enough water to pump it in the system and the engine is naturally overheating. I checked the impeller and is in order. When i've put it all the pieces of the pump back together, i did it under water and the pump being full of water, everything went fine, but as soon as i'm rising the stern, i've got the same problem. Please help me with this!

Since this is an outboard forum,and you have expressed an I/O question,one might expect no response.However I shall try my best to answer your quandry.At the bottom of that water pump housing, you will see a rubber hose that feeds into the lower part of the drive.Is this hose clear?
