Thank you. I hope for carburator/fuel pump issue and as long as it runs like normal until about 3800 I hope comp. is ok. Do you know if this carburator has a kind of 2 step function?
My engine runs nice until I reach between 3500 and 4000 rpm. I usually get 5000rpm. This is a Mercruiser 3.0 130HP from 2005. The fuel filter looks good and I bought new ignition system one year ago. Any suggestion??????
