Need to know what you have. FYI not all shifters have a button for throttle only. On some, the whole lever will slide towards port side to get in the throttle only mode.
EDIT: FYI again. If you didn't know already, the engine should not be revved very high while on the muffs.
If there is no button, you may have to put it in neutral and pull the shift lever out and move it forward for throttle only.
If it won't pull out, post a picture of the control. You may have a different control from what Mercruiser used.
