I remember when Tracy was at Pepsi-Cola & Nabisco. Will he be moving into a new position at BRP, or moving on to another company? Be great to follow him.

If I understand everything correct he is completely gone from BRP as of today.

1931 Winner of the 132 mile race from Albany to New York City. Photo shows the winner Red Woodworth, a renowned football player of the time, crossing the finish line. His time was 3 hours and 10 minutes at an average speed of 41.8 mph. Red’s boat was powered by a 1930 Evinrude Model 178 “Four-Sixty Racer” (know as a 4-60)

The motor is the grand-daddy of the Class “F” racers. Its name is derived from the four cylinders and 60 cubic inch displacement. It’s an “opposed” engine with two rotary valves in the center of the crank (one for feeding the top cylinders and the other for feeding the bottom). Ball and roller bearings are used on the mains and rollers and needles are used on the big and small ends of the rods, respectively. It was originally sold with a large muffler but most of these were discarded when racing to reduce exhaust back pressure. Battery ignition was used for ease of starting and to enable the use of a smaller flywheel (to reduce rotational inertia). The large ports were free-flowing and aggressively timed. Its performance on gasoline was never advertised but peak horsepower was achieved at 5000 rpm. Many of the old racers used methanol as a fuel to increase performance but because the cylinder heads on this motor were integral to the cylinder blocks, it was difficult to raise the compression ratio to take full advantage of the alcohol fuel.

OMC realized the shortcomings of the integral cylinder heads and later brought out “detachable” cylinder heads to make it much easier to modify combustion chamber volumes. The carburetor is a Vacturi Model A-500. The short tower and streamlined lower unit has low-friction bearings on both drive and propeller shafts as well as a water pump with a pick-up on the front of the lower unit, above the gearcase. Two-blade bronze racing propellers were offered by OMC as well as the after-market. One of the best attributes of the 4-60 was its durability, and this often enabled racing victories when vying against faster but less durable competitors. (see photo of the 4-60 below)
