Your speedometer paddlewheel could be sticking. Look under the boat on the trailer and flick the paddlewheel and see how it responds. If it drags a bit, it may need to be lubricated or replaced.

The speedometer is separate from the perfect pass speed pickup. If you flick the paddlewheel with ignition and perfect pass display up, then your display should read around 7 mph or so with an adequate flick.

The speedometer has its own pickup, and uses pressure exerted by the water to determine speed.

For help with perfect pass, I would contact perfect pass if unable to resolve the matter. They are highly knowledgeable about their product line and are happy to help you out.
