2702 2 cycle 40hp

Special design-High Torque/Low Rpm Engine. The 2702 produces 40 hp at only 5500 rpm while building an impressive torque of 39 ft lbs. at only 4500 rpm. Operating in an Rpm range 1000 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. The 2702 has an outstanding reliability record and is the only 40Hp on the market with dual ignition. Factory recommended TBO is rated at 1200 Hrs. @ 75% power.

2702 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. 2702 crankshaft is 4130 chromemolly steel. Heads, cylinders, rings, block casting, connecting rods and associated components are all of the highest grade alloys available
