Mercury 4stroke BigFoot 15hp smoking

[crotonpond]

I know its not normal for it to be smoking. I noticed after sitting a good week in the down position it smoked pretty good when i started it, but then cleared up right away. I then noticed at about 1/4 throttle I had smoke coming out of the exhuast port. Not a ton, and at 1/2 throttle it cleared up. Any suggestions?

Thats normal. Its more exhaust fumes then smoke. If you raise the rpms on your car. You will see fumes also
