That is odd. Wonder if you're dropping spark on one cylinder at lower RPM's? At any rate, I always like to start with compression to see what's happening. I'd keep the receipt for the fuel pump, I don't think it sounds like the culprit either.
Savland,Guessing maybe the motor doesn't start real well now either?Had a merc once that did what you are describing and the timing was out to lunch. Most of the rpm band was a mess, but wide open it would go. If you need the particulars, my manual covers your motor.I can email or fax pages if you need them.Don't know where you are getting parts, hopefully not from the guy right next to the Douglas bridge.Best prices I have found are here: http://www.newagemarineparts.com/ Good service on parts delivery.PS: Moving to Juneau in May. Can't wait!
Like to let people know it was a faulty fuel pump after all. I think there was a hole inplastic piece between engine and pump allowing fuel to flow into crankcase directly. Could not see the hole just a small crease in plastic. $45 fix. Engine now runs like knew.thanks for the feedback.
