I'm new to the world of outboards. I own a new 05, 25hp outboard and have used it twice in a lake. I'm still in the break in stage. I have 2 questions. 1. Is it normal for water to be coming out of the exhaust holes on the shaft? 2. After the first outting I parked the boat and trailer. When I went out yesterday I noticed what appears to be a dried up black residue on the inner part of my prop and on the blades. I ran the motor yesterday for about 2 hrs total and there is no reoccurrence of the mystery liquid. Is this gear oil? I know after the first 10 hrs of use I'm supposed to change the gear oil per the owners manual. I have a total of 4 hours logged on this motor.
