Help Please with E'Rude 15HP 1978 Wrong Coils Installed?

[SeaKaye12]

Hi....

New to me 1978 15 HP Model #15854B.

Previous owner said wouldn't start...so he installed 2 new coils. Still no spark. He gave up and the motor is now mine.

One thing I notice: Coils installed are #582508. Parts sites seem to indicate they should be #584561...but it's ambiguous.

Do I have the wrong coils?

The other thing that might be a factor here: The engine **MIGHT** have originally been electric start. It has the dual gear flywheel, a rectifier and junction block....and the exhaust access has the starter motor mount. Would this alter the choice of coils?

Can anyone help?

Thanks, Chuck

Coil #584561 is the proper coil and it DOES NOT supersede up to #582508.

I don't know what the difference is between the two coils but 584561 is what the engine calls for.

As I posted in your other post, the parts breakdown does not show any difference in the ignition system for manual start and electric start.

Thanks everyone. I e-mailed CDI earlier today and received an almost instant response; both of those coils should work. When I asked why CDI manufactured two different ones and what was the difference between them.....the reply was "mounting preferences by the market".

And; guess what? I was taking the PO's word for it having no spark. I just finished testing it...and it has GREAT spark. So there
Trust but verify when it comes to what a PO tells you I guess.
