gas mixture leak

[Eazzy]

I have an oil gas mixture leak that runs down port side of drive shaft housing on outside it is black in color and usually appears after shutting off motor. any ideas where leak is coming from ? It's a 1996 75 hp Force. Compression test is 125 127 128 don't think it's a head gasket leak. Motor runs fine. Your thoughts. Don't want to do a tear down without some input from others. Usually wipe it off with a rag twice when i get it home and doesn't appear again till i use motor again, It's just one of those things that sets in the back of you mind and says ????????

Normal. Unburned fuel. Collects in the midleg and runs down and out a hole placed there for just that purpose.

Just a little or a bunch?
A little is normal.
A bunch ,no.
A bunch,possible the fuel recirc system isn't working right.
You might need to replace all the hoses on the motor.
Ethanol is messing with older hoses.

I would call it a little a streak about 5-6 inches long usually have to clean it off twice once when i take the boat out of the water and again when i get it home. Thank's for the info.
