I took the boot off and tried to loosen the collar on the outside, but no 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. Dave
