Abstract: A method and tool for cleaning a watercraft speedometer are disclosed. The tool comprises a body, an extraction tip extending therefrom, and at least one edge on the extraction tip that can catch matter in the cavity. The extraction tip is attached to the body and is approximately the size and shape to fit into an intake cavity of a speedometer mechanism so as not to damage the intake cavity. The extraction tip edge is used for extracting debris from the intake cavity. Twisting the extraction tip into the intake cavity and pulling the extraction tip out of the intake cavity results in catching and withdrawing debris from the intake cavity.
