I would definitely check the voltage at the starter solenoid coil coming from the button. I found on my 37+ that the voltage was very low because C&C used very small gauge wire (22 Ga.) from the engine panel to the solenoid. This resulted in a significant voltage drop (5-6 volts) which precluded the solenoid from pulling in reliably. There are two solutions if this is your problem. Rewire the start button with at least 18 Ga wire, or put a relay next to the starter so the solenoid gets the full 12 volts to the coil. I put a relay in because I was too lazy to string all that wire. I've had no problems since.
