Low current draw
Extended Cranking Models are 24V Only
Light Weight - only 9.3 lbs
Replaces nearly all* original equipment starters on non-geared Lycoming engine-powered aircraft
Now used by Lycoming as factory OEM on most aircraft manufacturers' engines
For newer C206 or B60 aircraft, use 149-24PM
NL’s are the BEST starters for 6-cylinder lycoming engines and IO-390’s

The classic High-Torque Inline starter is the recommended starter for just about any flat, non-geared Lycoming piston engine application. Order the new SuperDuty NL/ec version for 24 volt aircraft or the #1 selling NL for 12 volt aircraft. Especially easy to fit for short-wing Pipers, retractable Cessnas, helicopters, rugged operations and harsh environments or applications with minimal clearance in front of and around the starter. NL/ec starters have been independently tested to repeatedly demonstrate over seven minutes of combined cranking in a nine minute period! Shear pin protected against kickback.

The Lycoming LS, PM & HT starters feature an integrated starter solenoid for homebuilt applications not wishing to install a separate firewall solenoid. Sky-Tec HT & NL starters feature Sky-Tec's exclusive KPS® (internal Kickback Protection System) that utilizes a shear pin to minimize starter and ring gear damage in the event of a premature ignition misfire event (kickback).
