A friend had a similarly problem on the weekend. We tested for spark and found one was not working as good as the others. Swapped coils and that changed nothing. Swapped plugs and the problem went to the other cylinder. Pulled that plug out and put in a spare and that seemed to do the trick.
I have one of those spark testers that clip on the plug wire. Bought it many years ago and have used it lots. I don’t recall how much but I know it was cheap.

Twinwinds said “just started it in driveway and almost sounds like one cylinder is not firing......its farting and backfiring
That’s what my buddy told me his motor was doing.
Guys, I was trying to answering twinwinds post to say check the obvious first before you send it to Mr. Bigbill.
He also said “Thanks for all the tips.....Wished i was a little more knowledgeable in engine repairs so i could fix it myself!....”
The average guy can and should test for the basic stuff. Compression, gas, air and spark. The average guy should be able to work on a 1994 motor. Or least test it before you send it to the shop. In my own way, I was encouraging twinwinds not to overlook the simple things first.
A better post by me might have been to send him to search http://forums.iboats.com or http://www.marineengine.com/boat-forum/index.php
Or tell him to check the basics compression, gas, air and spark and report his findings to help eliminate the working components and focus on the problem.
My bet for twinwinds fix is “send it in to the shop and let those with vastly more knowledge fix it.”
What the world needs is a wiki for fixing things.
Anyone know how to stop my microwave oven from flashing 1200.

Farting or coughing sounds more like a lean condition, or lack of fuel. That would be more common and would indicate possible plugged jets or circuits in a carb. It could just be an adjustment, but not likely if the coughing is bad and came on suddenly. Diagnosing on the hose is also not as easy as in the water. All engines run smoother or better mask issues without the back pressure from having the leg submerged. An engine may run fairly well on the hose in the driveway, but stall out when put in gear out on the water. A bad coil or plug should just cause a rough or shaky idle and a loss of power, not coughing and farting.

I had the same type of problem last year. It was not spuing gas out of the carb though. It ended up being a coil. I figured it out my self by seeing that the spark was weak on that cylinder. It would not run smooth at idle.New coil , problem solved.
