TAKING THE SEABEE FROM CERTIFIED TO AMATEUR-BUILT
When Brian Robinson faced an expensive engine overhaul to his 1946 Republic Seabee, his engineering talents and creativity led him to explore alternative options. Tired of 1930s technology with poor fuel efficiency and reliability, he devised a plan to develop a new power plant for his aircraft, moving it into Transport Canada’s flexible Amateur-Built category.
Extensive research led to selection of the famous V8 GM Corvette LS-series engine. This automobile engine offered the advantage of modern systems such as air conditioning, exceptional power-to-weight ratio, and high reliability. To this configuration he added a custom gear reduction drive alongside many additional safety features such as dual fuel pumps, dual batteries to meet aviation needs. Engine power was increased from 215 HP to over 450 HP with significantly improved fuel efficiency, reliability, and safety.
