0586323 coil specifications

[DoubleDot]

Hello everyone !
Recently got an 1998 25hp 3 cylinder J25RMECA and i think I'm having spark issues
in the service manual says that the coil P/N 584826 primary resistance should be 0.28 +- 0.05 ohm and secondary resistance my meter should show 2300 +-300 ohm.
the engine came with P/N 056323 (since P/N 584826 was replaces P/N 056323) and each coil shows primary resistance at 0.9 ohm and secondary at 253 ohm.
Ive look everywhere for 0586323 coil specifications but can cant find it anywhere .
My question for you good people at Iiboats.net is should 056323 coil read same values as 584826 coil from my service manual? or what the 0586323 coil reading should be ?
Any help will be appreciated !!!
Thank you .

I'm sure your probably fine...have you tried other test like a spark gap measuring tool?

Has the vro been deleted on that model? If not it needs to be.

Hi
Thanks for the response about the coils and yes Ive remove the oil mixing chamber - it failed at the 1st ride .
Since then the engine runs fine with lots of power but it struggle to idle -it shakes a lot and look like is running on one cylinder with no deference if I'm applying throttle or not , only kill switch stops it lol. Spark tester shows uneven spark when engine is in the shaking stage .
Ive rebuilt the carbs and fuel pumps,vac and fuel lines cheeked for leaks.
Compression around 100 on each cylinder .
Any ideas?
Ps My worries are that i need new power pack

Get a spark GAP tester. Check spark for 3/8. If you still think it's spark, have you observed the timer plate while it's running? I'd pull the flywheel and examine all the components and linkages.
