Hello All..   I have 2002 285ssi with twin Volvo Penta 5.7l gxi...   I have been noticing a missfire while under throttle on the port engine.  Can not figure out any specific situation that causes it.  It will missfire several times, run fine for awhile, missfire again...  Last week it missfired about 6 times within the first 30 minutes out.  Then again a few miles later and then not at all on the ride back to the slip.  I have replaced the plugs, wires, cap and rotor on the port engine and still missfires..   Fuel issues was mentioned but I think that would effect both engines, not just one.   Maybe a bad cylinder...  Haven't performed compression test yet.   I would think with a bad cylinder that the missfire would be a lot more prevelant than what I am experiencing...   Any help would be very appreciated..  This is starting to get a little frustrating....

Thank You
