I just bought a used '89 Mercury 25HP 2-stroke electric start. It has the remote controller, a Quicksilver, and I noticed on the cable coming out of the controller was an extra connector (4-pin). Looking around the web, it appears this is for plugging in a Tach cable. Since these controller cables are probably interchangeable on different years and models, I imagine that just because the connector is there, it doesn't necessarily mean it works with every model. Does anyone know if my model motor works with a tach? I hate to buy the cable and tach only to find it isn't supported.
P.S. First post, great forum! I've already purchased two orders from the store, great selection and prices!
