[Wink]

Posting for a non internet friend:<br />1977 Johnson 85 horsepower, It went simming underwater for 12 hours. Got it all flushed out, carbs cleaned and had to replace 2 coils that were cracked, But starts A ok, after the cleanup and oil down, however it will not stop when the key is in the off position, Probably a no brainer for you Outboard Guru's But .........<br /><br />WAZZUP ?

This is an odd one

<br /><br />Water in a relay in the ignition circuit?<br />Hmmm....Maybee water under the flywheel ,arcing the stator over?<br />U got me. Something is arcing over, and probably on the high voltage end of things,like coils.<br /><br /><br />------------------<br />"Honey,have you seen my boat keys? Honey? Where are you?"

Need to check the grounds at the powerpacks on mounting bolts of packs are making good connection that's were packs get there ground to shut engine off also check the red barrel main harness slightly spread pin to make good connection

well, replaced switchbox, same result, But what is odd is if you remove the ground from the plate which the switchbox mounts to engine runs fine, when you ground the mounting plate as it should normally be, it kills the engine. So WHy is when it is properly wired engine wont fire, remove ground and it runs OK, at least on ears, but cannot turn off with key, Circuit for key tests OK, did claen the big red plug also, So new switchbox, new coils. I guess this leaves stator???<br /><br />Any idea on what readings should see at sensor leads comming from stator?
