Model Number Explanation

From ClassicBoatWiki

Beginning in mid-1929 to 1935 Gar Wood used designations that identified the boat by length and speed. For example the "25-30" was the 25' Runabout (1932-1935) model with an engine which would give it a top speed of 30 mph. The "25-35" was the same boat with a larger engine and its speed was at least 35 mph. There was also a "25-45". Beginning in 1936 all Gar Wood boats were given the prefix "6" (for 1936) and listed in series. The 600 series was the 1936 version of the 16' Custom Runabout (1936-1940) and there were four models in that series (600, 601, 602, 603) each having a different engine and rated speed. In all other respects the boats were identical. The next was Series 605 which was the 16' Speedster and there were 5 models in that group. Once again the only difference was the engine offered. In 1936 there were 14 different series and over 100 "models". A series was a design style and a model referred to the engine used in that style. Gar Wood boats had a metal plate that identified the series and model. If your Gar Wood has a metal plate with number "746" then your boat is a 1937 version of the 28' Custom Runabout (1936-1940) with a Scripps V-12 316 hp rated at 45-47 mph. The same boat and engine in 1938 was model "836", and in 1939 it was "936", and in 1940 it was "136", 1941 it was a "36", and in 1942 it was a "231" and so on.

The one known exception to this system was for the 1938 22' Streamliner. Because it was a late addition to the 1938 lineup, and all of the 800-series model numbers had been used, it was given a model number of 915. When the 1939 models arrived, the 915 number was then designated as the regular 1939 22' Custom Runabout, and the Streamliner was given the model number 923.
