I have a Mercury 125 that when idling has a knocking sound. What can I do to stop this? Also at 2000 RPMs the engine misses. Runs good other than that.

Re: Mercury 125

What year is your motor? The first thing that comes to mind is out of time setting at idle or a faulty coil. How does it do coming out of the hole?
