Marine Engine
TT9568Thunder Tiger - PRO-21M A
race-proven PRO-21M power head is mated to a lower unit that utilizes
the best aspects of gear and flex-cable drive technology. A innovative design that is sure to increase the popularity of the 3.5cc Tunnel Hull class.
A
special set of precision helical gears transfers power from the
crankshaft to the flex-cable, resulting in substantially reduced cable
wear and maintenance, while the integrated expasion chamber (muffler)
reduces exhaust noise.
The Marine series are manufactured by
automated computer-controlled machinery, resulting in a product that
looks and performs better. The engine mount allows adjusment to both
propeller depth and angle with a Prather S215 propeller which is
included. Precision air bleed carburetor makes adjustments simple.
