1960 McCulloch Scott 40
The Scott-Atwater 40 was first produced in 1957. The name was changed to Scott in 1958 by McCulloch, who had bought Scott-Atwater. Bob McCulloch had raced boats in college and remained a racing enthusiast. The Scott 40 and 60 (made first in 1958) were popular in NOA OPC racing 1958 and 1959 where they enjoyed some success, especially setting speed records. The motors were not as fast as the Mercury Mark 58 and 78 in the same classes, but the Scott racing program was very good. They used Allison and Rose boats, which were faster than other production boats at that time. A Scott 40 set the record at 40.5 mph on an Allison in 1958, Joe upped the record to 42.5 mph with a Mark 58 on a porpoising Allison in 1960. The later record would have been higher without the porpoise.
The Scott had V-block reeds, the intake system of choice today but has a too long stroke and so doesn't wind as high as the Mercurys of that era. The Scott 40 was bumped to 45 hp in 1961 but in 1961 Mercury offered the Merc 500 with tuned exhaust. Nothing could run with that notor in the 44 c.i. class until OMC made the 45 c.i. 55 hp model in 1976.
This clean Scott 40, a fresh water motor from Michigan, still has good compression. What we did: replaced the fuel pump diaphragm, fuel lines, spark plugs and gear oil. Cleaned and adjusted the points, the condensers and coil are good. We had the bent bronze prop welded, then repitched it. This Scott is ready to run on a fast 12-14' sport boat or racing hull.
