The tachometer on the boat isn't working correctly. Just gives me crazy readings that seems to jump all over the place. Anyone have any idea where I should start to trouble shoot the issue? At higher RPM's the boat will give me a continuous beep until I slow the boat down. The boat runs great at 35 MPH (GPS). The boat has a 20 pitch prop. Just wondering if I should be getting a bit more speed out of the boat. Thanks for any info.
