Re: mist and exaust coming out of pee hole
The impeller should be replaced every 3 - 5 years (depending on use) regardless of it's visual condition. I think you need to do that for starters. The only other thing I would add at this point is you need to make sure the water level in your barrel is well up the leg, the higher the better. Many times the only reason it won't pump water is the level is too low. Try to get an OMC factory service manual for your hp and year. Either Johnson or Evinrude will work fine. Best of luck. Rick.
