Boat wont start

[dumbboatguy]

I did a dumb thing and hooked up my battery the wrong way. And then i tried starting it. I then realized i had hooked up the battery wrong and fixed it. I then tried starting it and it didnt start. First thing i did was check for spark which it didnt have. The engine cranks but doesnt fire. Then i checked for power to the coils which it doesnt have also. I made sure the shut off switch was working properly but there wasnt even power going there. The motor is a 73 20hp johnson. It just started fine two days ago. PLEASE HELP! Thank You

I think that model may have a fuse inline inside the motor compartment. If you are lucky that is all that it is.

Re: Boat wont start

the engine turns over with the starter, so the fuse is good. sounds like your reverse polarity, fried your electrical system. here are some test. http://www.boatpartstore.com/page29.asp

Re: Boat wont start

jumper wire from what to the coils. i hope it was not 12 volts, that will fry a coil.

Re: Boat wont start

did you try the test i gave you. it can be very costly working with out a manual. you probably fried the whole system. http://shop2.evinrude.com/ext/index.aspx?s1=bf6ad09c53cead335fcfd8a6471c0f7f

Re: Boat wont start

I suppose it just wouldnt have wrecked the magneto and maybe the condenser would it? I will try the test today and go from there
