50 hp merc rpms cut down sometimes

[macojoe]

if you have 4 I believe your looking at the coils, Not the power pack?? But I thought 50 was 3 cyl?

I have a V6 and there are 6 coils and 2 power packs, one for each side.

fallow the wire from th coil to the power pack, thats what powers the coils, you may have just one??

As for testing it, I have no idea how?? I just took a chance with mine, after talking to guys here and my own gut feeling.
I even got the right one the first shot.
