I bought it from a guy that bought it down south but the motor isn't the same one that came with the boat. The boat itself looks to be about mid 80s to early 90s from what i seen on google images but it has 1996 johnson 200hp V6
It ran last year then after winter I tried to start it and it never started up so i started checking for spark and their was no spark from all spark plugs so i check the volts from the brown/blue wire that goes to the coil and their was zero with the key on so i check the ohm's on each coil and 5 of them range from .250-.271 and the other one had .445. so now i'm not really sure where to look on the boat motor to figure out why theirs no spark. Any Idea? i was working on taking my flywheel off to check the stator but the flywheel doesn't come off, i already got the nut off but still the flywheel doesn't want to come off, do i have to get a puller for it? i modified a steering wheel puller to bolt it up to the 3 holes but still no luck ( i know its not the right thing to do but i didn't think the flywheel would be stuck on )
 
The flywheel can be pulled off with a proper puller ( hefty ), but the flywheel does not need to come off to check resistance of stator.----------------------The 12 volt battery is not involved in making spark on one of these motors.--------------Spark comes from the magneto when flywheel is turning.----------Did you check the kill switch on the control ???
 
no i didn't really check it, i just pulled the control box apart and seen it was nice and clean and everything was connected, but i notice when i turn the key to try starting it the brown/blue wire that goes to the coil would read about 12 volts when cranking but when the key is just on it reads zero
 
OK ---------On your motor the battery is used to turn the motor over ---------The battery has nothing to do with powering the ignition system for spark to the plugs !!!!!!!------------Spark is generated by the magneto ignition system and it does not need a 12 volts to do that.---------------When the key is "on " the kill circuit is open for ignition.--------When key is " off ' the kill circuit is closed / grounded.--------------This motor will run with a totally dead battery, trust me.------Hope this helps your understanding of it.
