My motor was running fine for years and by accident yesterday I hooked it up backwards on my new boat . When I pushed the electric start button the starter Spun, but did not engage I pushed it several times before realizing the positive lead was on the negative post. I had the wires reversed by accident. I corrected the mistake but Now the motor will not start...I have NO SPARK. Anybody know what I blew out ? thanks Mickey

I'd guess it is a power pack, but if you go buy a 12 volt circuit tester, you can trace your problem...work from the battery into the motor..

Does anything happen when you hit the starter now? Are there any fuses you could check?

I would be looking at it is if the little light doesn't come on, you know where the problem is...

If it won't turn over, something blew and will now allow current through...
