I have a 2011 Mercury 4 stroke 90 hp (I bought new in 2011) that will start and run fine at idle for 5-10 minutes. Once it warms up, it starts running real rough, looses power, starts smoking and dies. It won’t start again until it cools off. I have replaced the spark plugs but the problem still exist. This is the first time I have had any issues with this motor. Any ideas on what could cause issue or what to check to correct this issue would be very much appreciated.
