Tech Notes
           This is the Short Flexible Exhaust Pipe for the O.S. Max
                       FS-120III Engine W/Pump (OSMG0935).
       This Flexible Pipe replaces the existing header to allow rerouting
               the silencer farther away from the engine or cowl.

FEATURES: Uses the silencer that came with the engine, it replaces the header. Reroutes the exhaust to a more convenient location.

INCLUDES: One Short Flexible Exhaust Pipe for the O.S. Max FS-120III Engine W/ Pump with: Two pipe nuts. One pipe adapter.

SPECS: Length neglecting threaded part: 4.61" (117mm) Overall Length: 5.79" (147mm) (including the adapter) Thread Size on Nut: 11mm at one end and 14mm at the other. Diameter of Flex Pipe: 14.2mm (0.56")

REQUIRES: Threading pipe into exhaust port and tightening locknut with a 17mm wrench

COMMENTS: This pipe should not be bent in a diameter that is less than four times the radius of the pipe. Bends in the pipe should be as far as far as possible from the threaded part of the pipe. Final adjustment should be made in steps of only 2-3 at a time. Repeated adjustments to alter the shape of the pipe will weaken the pipe and cause it to break. This works on any 120 surpass engine
