Mercury 115 1988

Extreme loss of power when I initially start. Sometimes it will not even get my boat on plane. After engine has been running for approximately 5 minutes or more it will suddenly clear up and run fine usually for the rest of the day. I'm not sure but I believe it may not be running on all cylinders as the exhaust has more smoke than usual. This is the original OB on my 1988 Ranger 320V.
