Ive searched and searched and cant find anything that works..

I have a 1998 mercruiser 3.0l/alpha 1 sterndrive. The thing has run like a champ since i got it 3 years ago. This year im having a problem.. it starts no problem, and gets on plane no problem, but it has an intermittent issue where it will run great, then bog back for a minute, then it will kick back in and go back to my desired speed. It just bounces back and forth. I rebuilt the carb, the fuel is good and fresh, the filters are all clean including the pickup tube. Good sparks on all cylinders. Im running out of things to check! Help!!

Re: intermittent issue, help!

is the fuel tank free of loose debris that could clog the end of the pick-up tube??

Yes it is free, or at least from what i can see from the little hole that the pickup tube goes into.
