will MSD 8222 coil work with merc TB5 system
 
Doing a full tune up on my 1995 7.4 Merc, with TBV ignition. Wondering if the MSD 8222 coil (High Vibration) work with the TBV system? I see the primary resistance is within spec (0.7ohms) but the secondary on the msd is 4.5k - spec is 9,400-11,700 Ohms.

MSD coil is much cheaper than stock replacements, plus i'm finding that some of the "direct replacements" are not within primary spec upon a closer look.

I've tried asking this on other forums, but some of the marine community tends to be anti-aftermarket, and against the replacing of parts. No it's not broken but I like keeping components fresh. Thanks in advance.

Yes it works. Have several in the field. One is going on 18 yrs or so.

You can search this topic and i’ve chined in and discussed this a lot over the last 20yrs.
