Rotary Knob Under Dash

[ghebert1111]

Can anyone tell me what this knob is? I was poking around under my dash and saw this under the ballast rocker switches.

That's the turbo knob. Makes your boat go as fast as everyone thinks it does.


Nahh .... it is used to calibrate the speedometer/perfect pass if I remember correctly.

Wow, let me go back down there and... Aww Dang it.

Its not for Perfect Pass, its just to calibrate your Analog Speedo.

Use a hand held, or a phone app that gives you speed.

I personally like Speedometer GPS app, then you use that dial to fine tune the Speedo on your dash.

As long as it's not the ejector seat. Had a buddy a long time ago that had one of those in his car. I pointed at it and said, "What's that?" He screamed, "Don't touch that!" Had me for a sec.

Here's the boat version:
