Anybody good with merc's?

Ferm, Bigshrimpn, or Spare will be along shortly to have you fixed up.

I will give it a shot in their absence.....DO NOT LISTEN TO ME!!!!

Could be the power pack for that bank of cylinders or it could be the reverse cut out switch that someone else had trouble with recently.

Or something else that I don't know about.....wait for the experts to answer.

Sounds like a switch box gone bad to me. The easy way to diagnose would be to swap switchboxes from one side the the other and see if the problem moves with it. Ferm or Shrimp will be along shortly with a more detailed answer.

i would agree switch box you have two of them one for the left side plugs and one for the right side its easy to replace could also be the stator but sounds like switch box to me

Knock on wood, my MERC has been trouble free. If I had to guess I would say switch box though. Common problem for the MERCS to lose em. RAPAIR/CDI is regarded as being the better replacement for the switchboxes.

thanks guys for the quick response. i didn't know the switch boxes were interchangeable.. that will definitely be my saturday morning project, switching them around. i'll keep you guys posted. thanks again!

bad news guys i just switched both boxes around and i'm still getting no spark on the starboard. so now i eliminated the idea of a bad switch box what should be next on my trouble shooting?

boxes sounds good, still sounds like the stator. it probably isnt the trigger because that usually would give you two dead cyl, one on each bank. and if you still want to be sure bring it to a shop and tell them you want them to put their meter on the yellow wires tell you what they find. they probably wont charge more than 50 dollars.
