Special Design - High Torque/Low Rpm Engine
The 3202 produces 55hp at only 5500 rpm while building
an impressive torque of 53.2 ft lbs. at only 5000 rpm. Operating in an Rpm
range 1500 Rpm less than conventional 2 cycles results in a very smooth and
quiet running engine with impressive power. Fuel rate is lowered and TBO
increases.
3202 incorporates Al-Nikasil coated cylinders for
superior performance and reliability. Al-Nikasil in simple terms is a nickel
based material, applied in a paste form, when super heated it becomes part of
the cylinder itself. Al-Nikasil provides for a super low coefficient of
friction, reducing engine heat and wear. The pistons and cylinders expand at
the same rate thus providing for a seizure resistant engine. 3202 crankshaft is
4130 chromemolly steel. Heads, cylinders, rings, block casting, connecting rods
and associated components are all of the highest grade alloys available.
Factory recommended TBO is rated at 1200
Hrs. @ 75% power.
