Throttle shift handle question

[mr steve wayne]

I am a newbe, so please do not think bad of my question. I am restoring a 1984 Sea Ray with a Mercruiser 5.7.
I am working on my throttle lever, and the plastic piece behind the button is broken.
Can you tell me is it important?
What does it do?
Can I get another one?

Pictures would help.
What control do you have.
Is it the center button.

That looks like the old US Marine control. You can try eBay for a direct replacement or go with a brand new Teleflex or Quicksilver one.

Is Teleflex gust as reliable as quicksilver?
