hi
I am new here and needed some other advice
2004 90hp merc 2 stroke, on a skeeter SS90 bassboat
starts fine /idles great/ runs great
except at time the motor will miss (feel a slight bump) and tach jumps
and other times it misses like I a moving from half to full throttle, but is intermittent sometimes acts up sometimes not. what i noticed is long runs 20 mins or longer or misses
new fuel filter , onboard tank emptied and filled with new gas/fuel lines changed including bulb primer and carbs cleaned at merc dealer and still have this stumble
the tech said it happens when he turns the boat or hit rough water or waves
any ideas
cdm acting up
loose connection in wiring harness
