Beta 150_

The Beta 150 has been specially developed for commercial Fishing Boats, Launches, Wide
Beamers and Dutch Barges. It is a heavy duty – 6 cylinder – naturally aspirated – direct
injection – marine propulsion diesel engine. Its outstanding asset is the slow speed / high
torque of 450Nm developed at 1,700 rev/min from an engine of solid construction that is not
only smooth and quiet but also economic with direct injection. This engine is ‘Recreational
Craft Directive’ emission compliant, and EPA compliant.

The Beta 150 utilizes the NEF series FPT-Iveco N67-150 Base Engine.

Beta Marine – Beta 150 – 6 cylinder, naturally aspirated, diesel propulsion engine developing 147 bhp at 2,800 rpm with a swept volume of 6.7 litre. The engine is supplied complete with a heat exchanger and header tank, water cooled exhaust manifold, fresh and sea water pump, exhaust injection bend, mechanical fuel lift pump, fuel and oil filters, sump pump, flywheel housing, special quiet air intake filter, 12 volt starter, 90 amp battery charging alternator, shutdown solenoid, control panel “AB” (with tachometer/hour recorder, keystart switch and push button stop, warning lights and alarm buzzer for low oil pressure, high water temperature, no charge, and power on); a 3m interconnection cable with multi pin plug and socket to engine harness. Gearbox with nominal 2:1 reduction, heavy duty engine feet with flexible mountings, “Morse” type end fittings for speed and gear control, engine test certificate, operators manual. ‘Peacock Blue’ paint, packed on skid base and fully warranted by Beta Marine.
