  In this paper we present our study of the gamma-ray emission from the
microquasar SS433. Integrating over 9 years of Fermi-LAT \textsc{pass8} data,
we detect SS433 with a significance of ~13$\sigma$ in the 200 to 500 MeV photon
energy range, with evidence for an extension in the direction of the w1 X-ray
`hotspot`. A temporal analysis reveals evidence for modulation of SS433's
gamma-ray emission with the precession period of its relativistic jet. This
suggests that at least some of SS433's gamma-ray emission originates close to
the object rather than from the jet termination regions.
