Re: Is there different 'throw' lengths in the shipmaster and simplex controls?
The part that TD is talking about is called a "casing guide." He's right about the adjustment and this is part of what I was talking about in regard to the set screws. Since there is a little bit of variation in where the set screws can be tightened down on the inner wire of the cable assembly, you can get variations in the "throw" of the entire shift system.
BTW, the casing guide, and a part called the "casing guide insert" are the reasons why you can not use Type 479, press fit cables on a pre 1979 Simplex of Shipmaster control box. The later box has the same parts, but they are different. The casing guide has a pin that goes through the pressed on end of the cable, rather than set screws to clamp onto bare wire, and the casing guide insert is a different size.
I've also seen the problem that
F R is talking about. In fact, I even cut the wire on a shift cable once, trying to fix the same problem that you have. I was still teaching myself all of this stuff at the time and just made a mistake due to inexperience. At the time, the cables only cost about 20 bucks, so it didn't "hurt" too badly when I had to replace the darn thing!
To get a better look at the inside of your control box, you can go to the "OB ACCESSORIES" section of shop.evinrude.com. If you have the set screws, go to any year prior to 1979, then go to "remote control" (year will show) and then "remote ctrl single motor."
As
F R mentioned, the original Simplex and Shipmaster controls (50s version) are built somewhat differently than the later ones. These units are identifiable by their smaller size and rounded shoulders. I don't have any diagrams to look at, but if I remember correctly, the shift and throttle handles have gear teeth on them (internally), and so do the casing guides. The casing guides also have the set screws in them, so the same problem that TD is talking about, as well as the one
F R is talking about, can occur.
Here's a link for model number info on Viking engines. I had seen something else that suggested that a 1963 would not be a 25hp, but this indicates that it could be. There is a little confusion on the subject, because the OMC built Vikings ended when the Gale division, where they were made, closed during that approximate time frame. Apparently the later engines were Chryslers. Given that the OMC Vikings will have the powerhead, midsection and gearbox of the non-Superquiet 35hp. 28hp and 33hp motors, however, there won't be any doubt who made yours. In fact, if yours is a '63 and OMC built, it should be essentially identical to 28hp Rude or Johnson.
At any rate, you have a cool motor! I keep thinking that, if I end up with a vintage boat project, I just might have to go find a Gale or Viking to put on it for the "cool factor!"
