I have a 2006 4 stroke , bought in 2008, hardly used . Ran good the first year then when I started it the second season , I noticed it was vibrating too much for a 4 stroke. It is still under warranty and I have been trying to get the local dealership to look at it but they are so busy that I keep getting "give us a call next week" . Anyway I am trying to resolve the problem myself now. I have checked the plugs and they look ok. I have pulled each plug wire while the engine was running and it started to stall on each one so that tells me they are firing. Could I have the plug wires reversed?? I switched the wires and it starts and runs with the wires on either cylinder?? I just let it start and shut it right down.
To be sure can someone tell me , if I am facing the coil which wire goes where. Does the wire on my left ( towards the front of the engine) on the coil go to the top cylinder or the bottom one. At least I will know that's not the problem and can look elsewhere.
Any help would be much appreciated.

Thanx
William
