[Start by removing the throttle only button. It pry's out.]
Good post havasu, But you for got one step
The only way you can remove the neutral button with out breaking it is you need to push the center button in, And lift the red handle, Then go to W O T. Then pry the button out from the back side of the button head with something like a small flat bladed screw driver. Try not to damage the paint on the shifter while prying it out. Then go to neutral, You will then need a 11/16 socket to R&R the center nut. The nut should have lock tite on it already, But you should add a little more while putting it back on. I believe the specks is [150] inch pounds. When your done just push the button back in while it's in neutral. That is a insiders trick that I should have not really told anyone so the service shops out there can stay busy in these hard time.:redface:

PS, Havasuboatman just so you know the insider statement was not toward you, Sorry if you took it like that, Just meant it in general is all:redface:
