Oddly, the 23' Commander got a different throttle and gear selector than the 19' Commander. I'm puzzled, because I understand the larger boat also got the cable drive steering (see friction knob), while the smaller Commander got the shaft drive steering.
BELOW: A documentation of the 23' Commander steering wheel (same as my 1966 20' Sea Skiff), gauges, and gear selector.
Looking at the cross-pollenization between models at the Chris Craft Corsair Division, who built the small Commanders, and looking at similar features on the Lancers, Corsairs, and Sea Skiff's, I'm seeing some interesting mix of features for my next trivia contest:
My 1966 20' fiberglass Skiff has the same steering gear and wheel as the 23' Commander, and the same gear selector as the 19' Commander Super Sport. I suspect hull construction is very similar between these models, and it's "all good news" as far as I've seen. The strangest thing I've seen is the 1969 19' Super Sport has the same steering gear as my 1956 wood 17' Sportsman. They must have used that same steering on thousands of boats, and had a good stock left over.
In my 1966 Skiff, there are NO fiberglassed wood stringers, and NO wood that touches anything wet. Therefore, engine stringers are as good as the day they were cut. Awesome to find a 40-year old boat in this kind of shape, and it's a tribute to Chris Craft.
Study up for that pop quiz!~
