Marine Engine

TT9568 Thunder 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.
