Occasionally you will get a push button that will not cooperate. Worse case scenario grab the back of the switch with water pump pliers or vice grips and drill out the center of the switch. Start a little undersized as it is likely that the switch will break off. The push button will probably be able to be ripped off the switch with pliers allowing you access to the center. Good luck.

That is why I am not sure there isn't some hidden trick. Sprayed it with PB Blaster and will try again next time I am on the boat. It is possible that the PO put a different push button in, but I can't find anything like that one in the Cole Hersey catalog. The other push button and the new ones all have boots that pop on. This one the boot seems more securely attached, which might be more weather resistant. I think the outside collar actually trapped the rubber boot.

As an alternative you can cut the rubber boot off and grab the outside metal with a pair of vice grips or something similar. Sounds like it is no good anyway so tearing it up shouldn't be a problem. Regarding different switches, one may have been replaced in the past or have a different amperage rating than the other.

I had bought a new Cole Hersee key switch and two push button switches for the replacement. I was able to replace the key switch and the glow plug button easily (only a small amount of blood and pain). However, I realized that the original push button start switch is different from the glow plug button. The glow plug button has a rubber hood that can be easily removed and a knurled round collar nut on the outside and another nut on the inside to secure it. The start button has a rubber hood that appears not designed to be removed and a rounded collar piece with no knurling that secures it on the outside. I have been unable to remove that collar and it is not clear if it is threaded. The inside nut is different as well, and it is so tightly spaced to the body that I have not found a tool thin enough to get to it and loosen it. Anyone have suggestions on: 1. Why these two push button switches are different when the presumably perform the same type of function?2. A flat tool that can get to a narrow space for a large nut (something like a bicycle pedal wrench but adjustable)? 3. How that start push button switch is supposed to come apart?
