The Aeromarine 90 hp was the first aircraft motor built by the
Aeromarine Plane and Motor Company in 1914. In that year, Aeromarine had acquired the patents and manufacturing rights to the aircraft and engines of the
Boland brothers. Although the Boland brothers didn't make a 6-cylinder engine, their V-8's all used the unusual concentric valve that is used in this engine. In spite of its model name, this engine only produced at 1,400 rpm
