The motor that provides the power. In the past, the
primary engines used were large 12-cylinder Rolls-Royce airplane engines. These days,
almost all of the hydros use turbine (jet) engines. The PICO American Dream powerplant is
a Lycoming T55L7C Turbine capable of producing over 3,000 horsepower, which will turn a
drive shaft and three-bladded PICO propeller in excess of 15,000 RPM. The fuel burned by
these engines is aviation jet fuel or "Jet-A".
Also called simply the "prop", the propeller is
the component that actually moves, or "propells" the boat. Propellers used in
hydroplane racing may have two or three blades. Many of the propellers used in racing can
cost upwards of $10,000 to $15,000 each.
