New, just bought, Mercury 60hp 4stroke but a 2016 model

New motor. Did the brake in following the instructions. After 10 hrs changed the oil. The motor improved during brake in, is now more powerfull but it does not idle well when cold started, it's irregular. When I give it a little gas it feels like it'll die out but it does not. Very good idle when hot. Now at 25 hrs and still acting the same on the first cold start.
