Is there an easy way to adjust a speedometer on a 1982 Bayliner 1950 Capri,
It shows my top speed at 35 but a radar gun is showing 42. I have a 125
Volvo IO. This is a putt around the lake boat and being an old boat there
are a lot of things I would rather put money into than this but if there is
an easy adjustment that would be great.
