I just bought this motor and having a little trouble starting when cold .Could someone give me the official starting procedure for this motor . I hear there is one but I cant find it . Its a 2002 merc 150 saltwater. I had a 96 Johnson before and had no problem just choke it and it started . This is a different critter. After I get it started it just takes a touch of the key and it fires right up and runs great .
