My 15 hp 4 stroke mercury had some oil coming out of the exhaust on the driveway. The motor was tilted up as I was working on the boat prior to launching for the beginning if the season . I ran it for a couple if minutes eith water attached and when the water dried up, I noticed the oil. Is this a problem or normal
 
Not normal on a 4 stroke. You will need to determine if it's gear oil (leaking lower unit) or motor oil (power head).
 
Thanks. Its black motor oil. I changed the oil last fall when I put the boat away for the winter so the motor has new, clean oil in it.
