I have experienced this event three times recently.
I start the engine the tach is registering 2000 rpms. When I get her up on plane the tach is registering 5000 to 6000 rpms. I bring it down to idle again and the tach registers around 1000 rpms. Push the throttle up get on plane and the tach registers between 3200 and 4000 rpms. depending on the speed I am going. What gives!?!? Should I worry!?!?!?

"Cap,

The tach may be malfunctioning, or it could be that the stator is going bad. The tach uses the stator as an indicator of engine rpms. You should notice low battery voltage if the stator is going bad.

Thanks for the response Tony!
What is a stator?
Can I fix it myself?
