4.3 GL throttle question

[alan-bc]

I just bought a boat with a 2000/2001 4.3 GL.

The throttle is a whole lot like the one on my outboard, Fwd-Neutral-Rev with a trim switch on the left side of the handle.

However, under the handle is a white rocker switch, and I have no idea what it's for.

Any hints appreciated.

Ayuh,.... Push the button, 'n listen to see what it does,..... Probably a trailer tilt button,....
