    Looks like an exhaust leak to me. The exhaust coupler between the engine and lower unit is likely not sealed properly at one end or the other and unburned oil is leaking out.

    Bob and Bubba will be along shortly to give you their take on it, but my money is on an exhaust leak.

    Get a service manual and drop the lower unit, clean it up and put it back together according to the manual. Replace the water pump while you're in there.

    Then that oil is most likely unburned fuel. did you do a lot os slow running that day and what type of plugs do you have in it and what rpm's does it turn.

    Go get you a set of champion QL77JC4 plugs and set the gap at 40 and when you do a lot of slow running with that engine just take it out for a good hard run at WOT before you put it away.

    Johnny you need to let me know how many RPM's that thing is turning at WOT and if the carbs haven't been rebuilt in awhile you need to start putting things together to rebuild them. The unburned fuel is an indication that the enging isn't running up to par now a new set of plugs will help for awhile but you need to rebuild the carbs and fuel pump to ensure that the engine is running at 100% to make it last a long time.
    Most outboards don't die from over use they die from abuse so keep it running at tip top shape and it will give you several hours of good service.

    Willard is their some kind of tool i can get to tell me rpms cause i dont have a tac on the boat, I bet the carbs do need to be rebuilt cause the boat set up for 3 years before i got it and at about 2/3 throttle it will run across lake like a kitten at about 30 mph and at full throttle it will go probally bout 45 mph but it boggs. So what kind of cost am i looking at.

    You need to get you tach for it. I'll look around in my stuff and see if I have an extra one. If it boggs at WOT then they need cleaning. Post me the model number and I'll run down the parts number and you can check at your local Oriely's or Napa parts store on the cost.

    And btw they look fairly new like they may have been replaced.

    Johnny looks are deceiving. If it sat for three years previous to you useing it then the carbs need cleaning. If they set a year without being stored properly then they need rebuilding. This is a fairly easy task.
