  We report four novel position angle measurements of the core region of M81*
at 5GHz and 8GHz, which confirm the presence of sinusoidal jet precession of
the M81 jet region as suggested by \cite{Marti-Vidal2011}. The model makes
three testable predictions on the evolution of the jet precession, which we
test in our data with observations in 2017, 2018, and 2019. Our data confirms a
precession period of $\sim7~\mathrm{yr}$ on top of a small linear drift. We
further show that two 8 GHz observation are consistent with a precession period
of $\sim 7~\mathrm{yr}$, but show a different time-lag w.r.t. to the 5 GHz and
1.7 GHz observations. We do not find a periodic modulation of the light curve
with the jet precession, and therefore rule out a Doppler nature of the
historic 1998-2002 flare. Our observations are consistent with either a binary
black hole origin of the precession or the Lense-Thirring effect.
