Swap the wire to the coil with the top or bottom (not the plug wire) and see if the spark is better on a diff. coil. If not could be powerpack.

Re: intermittent spak?

marineengine.com has diagrams of your motor...look under the distributor group...you don't have an ignition system with a powerpack...try outboardbooks.com or ebay for a factory service manual...clymer and seloc manuals may not be specific enough for your motor... I personally can't offer you a starting point for diagnosing this ignition

Re: intermittent spak?

You only have one coil on that mtr which goes to the distributor cap. You could have bad coil, dist cap or amplifier. There is a test procedure to check this system out and found in the OEM factory service manual.
