[CA] [CA11] ST60 Speed Display Problem

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum WinniBoater,

The reported problem may be rooted in the transducer or the instrument display itself. Please click here to view a FAQ addressing how the speed transducer may be tested. Should no fault be found with the speed transducer then the speed sensing instrument would need to be replaced, as Raymarine can no longer service ST60/ST60+ instruments. As Raymarine i50 and i60 instruments, feature communications circuitry which will support either SeaTalk or SeaTalkng/NMEA 2000 communications, these instruments may be used to replace ST60/ST60+ instruments. Raymarine offers the A06047 / 15.7in (0.4m) & A06073 / 39.4in (1.0m) ST1 Adaptor Cables to permit i50/i60 instruments to replace ST60/ST60+ instruments within an existing SeaTalk bus.
