Mercury mechanic needed.asap

[RigRatNoMeaux]

Between lafayette and Lake charles, where are the best mercury mechanic? That big black b**** on the back of my boat is giving me some issues. First off its leaking oil and I can't find it, and now the new problem is knocking sounds. I was running about 5k rpms and she started to lug down, when I throttled back she killed on me. She started back up after a few tries but had a new sound and some vibrations. When I was getting back on step it was very sluggish but still did it. Definitely don't have full power. I thought it could be a CDM. So I checked all plugs for fire and I'm good. What do yall think?
