"Is this actually a case that there is no spark or simply that the engine won't start? That is, have you actually removed the spark plugs and checked the spark?

If so, and there is no spark, disconnect the large RED electrical connector at the engine, then check the spark by jumping the starter solenoid (small jumper wire from the battery terminal of the solenoid to the small 3/8" nut that energizes it).

Do you now have spark?

If so, check all connections related to the electric starter.... remove, clean, tighten all of them including the ground cable at the powerhead and the related components that the cables attach to.

That engine must crank over at least 300 rpm in order to energize the ignition."

THANKS JOE I know you can't tell if the powerpack is bad and wouldn't hold you to any advice you give. I ordered a new powerpack here at marine engine cdi. Thanks again for your replies.

"Even if the problem isn't the powerpack at the present time, that replacement will eliminate it as the problem area.

Always a good idea to have a spare pack in your boating toolbox anyway, along with the necessary tools to replace it. One never knows when they might fail BUT it's usually doing a holiday boating outing. The spare pack would save the day."
