I have a 91 Raycraft V156 boat w/a1980 85 hp Evin-<br />rude motor. I would like to add a tach and speedo<br />to the boat. At the transom I see two wires that<br />look like they're wires from the tach harness.The<br />boat the engine can from(which is mine too) came <br />with a tach and speedo. My question is where do these two wires go on the motor. The boat really hauls butt, but I would like to put a tach on to<br />make sure I don't over rev her.
