I have a good Datamarine speedo for sale. Includes display, transducer, plug, wiring. Works fine. I'm replacing my instruments with upgraded Raymarine electronics. $100.00. I'll pay shipping.
Bob, Do you know what the dead rise angle is for the depth transducer, for mounting in the area by the mast? Appraently there is a choice of three angles 0, 12, and 20 Degrees.
