Dumb moment....check your spark plug wires

[tomandwendy]

Wellllllllllll I am embarassed for this but decided to share it anyways. This weekend I was not able to get out to the lake and I decided to do some pm.....I checked the compression......looked good all withing 2-3 from each other.....but when I started the engine back up with water running, I have always noticed it seemed to be missing at low idle.....so started messing with taking one wire off the spark plugs to see where or if I could see a difference.....low and behold....I noticed to wires on the left side that there was no difference at all....after looking closely to each side....The company I bought the boat from decided to change the spark plugs and switched the left side wires to the wrong spark plug

and of course I have been wasting gas, underperforming, just basically sucks lol......so everyone check your wires! could be a gas saver!
