intermitten fire 84 evinrude 115

[droptheline]

I have an 84 evinrude 115 that misfires or quits all togather on the starboard bank. all wires coils & plugs are new and the dealer said that the timer base was bad and replaced that, power packs test good but still have the same problem, idles on all four, put it in gear past 1/10 throttle right banks cuts out, at half throttle it will misfire on right bank and past that it quits again. Its definitley an iginiton problem and any help in a forward direction is greatly appreciated.

1 - Check all rubber connection plugs. Pin and socket connectors have been known to be pushed back slightly resulting in poor contacts. Also the wires attached to the pins/sockets have been know to break away, barely touching resulting in weird happenings.

2 - Remove the black/yellow wires from the powerpack(s). If this causes the problem to cease, replace the ignition switch. (Note that with these wires disconnected, it will be impossible to stop the engine with the ignition switch).

3 - Observe all wires that move when the throttle is increased. Check the continuity of those wires with a ohm meter.
