I have a 2000 410 dancer with twin 454 mpi 380 hp gassers. The starboard engine has a slight rpm intermitant drop of maybe 100 rpm or a little more. Just enough to make my sync gauge jump around, and you can feel it if you are paying attention. When I throttle up real slowly it is not as bad or doesn't do it at all. When I am first leaving for the day it is most likely to happen. Does this sound like an electrical problem or a fuel problem? I've had a mechanic tell me I need a new wireing harness. Is their a fuel filter other than the fuel separator filter? Any help on this matter would be appreciated.
Thanks again
Gus
