The excitation function for production of 262Bh in the odd-Z-projectile reaction 208Pb(55Mn, n) has been measured at three projectile energies using the Berkeley Gas-filled Separator at the Lawrence Berkeley National Laboratory 88-Inch Cyclotron. In total, 33 decay chains originating from 262Bh and 2 decay chains originating from 261Bh were observed. The measured decay properties are in good agreement with previous reports. The maximum cross section of 540_\ensuremath-150+180 pb is observed at a lab-frame center-of-target energy of 264.0 MeV and is more than five times larger than that expected based on previously reported results for production of 262Bh in the analogous even-Z-projectile reaction 209Bi(54Cr, n). Our results indicate that the optimum beam energy in one-neutron-out heavy-ion fusion reactions can be estimated simply using the optimum energy rule proposed by \ifmmode \acuteS\else 'S\fiwi\katecki, Siwek-Wilczy\ifmmode \acuten\else 'n\fiska, and Wilczy\ifmmode \acuten\else 'n\fiski.
