Re: Ship Master Controls
The Shipmaster controls are the Johnson version of a control box that was used from the fifties through at least the early 80s - I haven't actually looked to see when production for them ended. There is also an Evinrude version, which is called a "Simplex" control.
The earliest versions of the Shipmaster and Simplex controls, were smaller than the later versions and had rounded shoulders. The internal mechanics of them were also somewhat different. The later boxes were larger and rectangular in shape. Both the rounded type (older) and the first years of the rectangular type controls, used Type 400 cables. These are the ones with end fittings that are attached to the cable via set screws. Starting in 1979, the end fittings were press fit and were referred to as Type 479 cables. You can buy both, right here at iboats.
Be sure that you have the correct cables for the box that you have - they are not interchangeable. You may find a part number printed on the casing of your old cables, which you can use to order new ones. If not, the salesperson can help you determine the correct length for your boat.
