Guys.... I took out my boat twice in past three weeks and it runs solid all the way up to around 4-5 rpms where it feels sluggish and under powered. Kind of missing some umph. It idles fine and never stalls around docks. I was thinking maybe bad fuel so I put some fresh 91 octane in and got some speed runs done but still struggling and missing at higher rpms. It did the standard 100 hour Mercury tune up around 150 hours back. Anybody have any clues..... my mechanic moved to NC and I have a new one referred but before I pull him in I'd like to hear from our inmate mechanical types on opinions. Thanks fellas.
