Engine misfire Over 2000rpm
Having engine issues with my 2400SC with the 350 MAG Mpi engine. When under load it misfires badly over 2000rpm which then also causes vibration from the engine. In neutral it revs up no problem well over 4000rpm so whatever the issue is it is only happening when under load when engine is under more strain. Something is obviously breaking down at that point. I know there could be numerous reasons for this but was wondering if anyone had the same problem with this engine? My local boat mechanic has already cleaned the distributer with no effect. He is going to check the compression this week to see if there is a problem with any of the valves. If it's not a valve I'm guessing it's an electrical fault.... any advise or help would be appreciated.
Thanks,
Ernie
