F6T405 ignition coil or 83575M

[wiwill61]

Hello everyone,

I'm looking for an ignition coil for my old 2-stroke engine, mariner 40BE 676BL404014 1978 (I think), they are original coils F6T405 was told that we could put 83575M or 83576M coils.
But unfortunately all these coils are found!
Would there be other equivalences?
Or find its coils?

I'm not a pro mechanics but I think I have a HS coil, currently I have two coils F6T405 I've tested has an ohm meter gives me strength 11Kohm and other 6Kohm I think so I have a HS. What do you think?


FYI my engine trouble keeping idle and lack of power in strength.

Thanks

Don't know about the coils, BUT, has the engine been sitting for awhile, NOT being used?

Idle issues and crappy running in general, if its been sitting or no stabilizer used, points towards dirty carbs...
