"Well, I really screwed up. Was comparing the tach in my boat with a Tiny Tach, to calibrate it. Not getting a decent readings from the Tiny Tach, I got some aluminum foil to place over the other ignition wire and shield it from EMF interference. I've doen this before and it worked great, but I wrapped it tightly around the wire, not draped it over it.

Guess what? The EMF charged foil touched against the low voltage terminals of the ignition coil and blew out a perfectly good spark box. Damn and double damn! I watched the boat tach slowly drop to zero rpms with the motor still running--barely--and then it went away totally. No spark.

We live and learn...

Got a Merc 40 hp twin given to me (I helped the fellow work on it for years) and--guess what?--it has the exact spark box I need!

Sometimes I get lucky.

My 83 40hp has been flawless since I got it. the 35hp (parts doner) is the same except for decals and switchbox wiring."

I'll save you a piston and

I'll save you a piston and rod when I rip it down.

Anything else you need?
