    My 2008 227 is great, except when hitting a "bump" that shuts down the engine. All saftey swithes work, and the mystery is that the engine turns over, but does not start. Waiting an hour or so, the engine starts. This has mistified the dealer as well............

    Thanks, possible good solution to mystery. I wall thinking that one of the saftey switches cut out engine and flooded it. Did pull one plug, looked possible, cleaned & replaced--still did not start. The mercury switch may be it , will check it out. Thank you.

    Assuming you really did make sure that none of the safety switches are at fault, I would second the coil diagnosis.

    There exists a way to check a coil with an ohm meter, the testing procedure is available
    online but it's not for everybody, some people get it, some don't (for example I don't).
    Unfortunately without a specific coil test, the only way to find out for sure is to replace it with a known working one.

    Here's a link to an ohm coil bench test but of course:
    *You'll need the resistance specifications for your specific coil in order to perform this test.
    Consult your service manual for this information.

    Thanks for advice. Will check coil and double check on saftey switches. Will post if the "mystery" is solved. Not sure though if this is it as the unit will only stop when "bottoming out" so to speak as rough terrain at higher speeds does not affect it.
