Your Question
First time out in our 09 BL, 4 cyl Merc. engine quit - started easily but would only idle, die in gear; then after a few minutes it ran rough with erratic throttle. A steady throttle would wander from 2300 to 2600 rpm.
Limped back to river dock @ around an unsteady 2500 rpm, where it would rev ok, but in gear the throttle was so undependable I wouldn't take it in to the trailer with someone in front of it. Anything more than a little throttle would suddenly surge. So we cranked it in. Obviously fuel delivery? thinking maybe a filter? or bad gas? I'd just added 14 fresh gallons to fill a 21-gallon tank. Don't know how long the first 7 gallons were in there but it ran out fine when we ck'd it out 3 weeks ago. Any ideas? Thanks.
