    2012 mercury pro xs problems

    So I'm not good at explaining this but here goes so I have a 200 pro xs that has lost about 7 mph and now is idling rough it first started on blast offs where when I would run to my 1st spot it surges bad kinda like it feels when u bump something running around it will do that every 10 secs or so...but then after the first run of the morning I can stop and fish and it wouldn't do it again but now its constant...and it only does it when I'm above 5000 rpms...I am gonna carry it to a mechanic but there's not alot of trustworthy guys in my area so any input would be nice to know from u guys...thanks in advance!

    Best for you to post your question the 3L forum (what your engine is) and be sure to include your engine serial number.
