"got a mercruiser 350 mag 1992
"got a mercruiser 350 mag 1992 (carb). this thing will idle fine, you can rev it in neutral, runs fine, you get out on the lake and through out different rpm's it bogs and sometimes stalls.. Its real intermittent, not really easy to troubleshoot.. I have changed out fuel filter, gas, plugs and even took the carb apart and cleaned it out really good.. It seems like something maybe plugged then comes unplugged or i may be loosing fuel pressure. it will bog out and stall, but start right back up and run completely fine.. when it does bog out i am definetly not on all 8 cylinders, then all of a sudden it is back on 8 and run fine.. i can creep around the lake just fine but when i give it gas it starts its crap again.. sometimes i get on plane sometimes it will bogg out before that, its all over the place and still feels like it could be a fuel issue. i did have a problem with some gas that i put in it, borrowed a tank from the neighbor and wound up having particles in it.. i drained the tank with a syphon and put new gas and filter in it and it ran fine for a few days then now its acting up again..when the boat moves around like bow going up or hitting waves it acts up.. maybe the pick up in the tank clogged?? maybe a fuel pump?? need some advise here..
thanks
