    99 speedster sk mpem

    I have a 99 speedster sk with twin 717 and it does nothing. Lights, blowers, bilge and all are fine but no start. No beeps unless you you try starter button approx 5x and give 2 quick beeps then dead. Figured mpem was bad, got another, exact same situation. My scanner does not recognize it. Last one I bought said it was keyed to the mpem but I can put 20 different keys on it and all the same problem. Spent 30 hours tracing wires and such and all leads me back to the mpem. Does anyone have a speedster I could send to see if these units are dead or an actually fully working mpem. Please let me know. I'm going crazy over this jetboat.


    Thanks,
    jessie

    My mpem number for my 99 speedster sk is:


    204470184
    And work with these only:
    1998-1999 SPORTSTER 1800 / 1999 SPEEDSTER SK


    I was sent a mpem that cross reference to:


    204470139
    Works with these boats
    1998 CHALLENGER / 2000-2001 CHALLENGER

    The guy says it will work but I have my doubts. Any thoughts?

    thank you for your time!
