Welcome to the club! I'm refitting a new to me old C&C Mark II 27 that once lived in Toronto and then migrated to the salt.

I'm not clear on the sequence that does and does not produce a spark for you. There are two situations I'm imagining you doing:
1. Set ignition switch to on, press start button: no spark (how are you checking for spark?).
2. Ignore start button, set ignition switch to on: get spark.
Why no spark in sequence #1, if you get a spark in #2? Or am I misunderstanding?
If simply turning on the ignition switch produces spark, then is the start button OK?

I didn't notice anything in your post about the wiring and wiring connections, and second the motions by pater and msmith10's to check wiring. You might want to carefully inspect or simply replace the wiring and connections in the ignition circuit from starter to ignition panel to coil. I have encountered old wires that looked OK on the outside, but were black on the inside.

If your boat's wiring is original, the schematic posted here http://www.moyermarine.com/forums/showthread.php?t=1341 for a 30' C&C looks very similar to the schematic in the 27's manual. If you don't have the manual for the 27, check out http://www.cc27association.com/ and http://www.cncphotoalbum.com/index1.htm.

I ended up stripping all the old ignition panel and wiring out of the boat, and have been rebuilding with modern schematics and modern parts to be on the safe side. That's a bit drastic, but this is my third boat, and hidden wiring problems have caused bugs for me in the past, so I want to start with a clean, known electrical system.
