  The nuclear recoil effect on the $^2 P_{3/2}$-state $g$ factor of B-like ions
is calculated to first order in the electron-to-nucleus mass ratio $m/M$ in the
range $Z=18$--$92$. The calculations are performed by means of the $1/Z$
perturbation theory. Within the independent-electron approximation, the one-
and two-electron recoil contributions are evaluated to all orders in the
parameter $\alpha Z$ by employing a fully relativistic approach. The
interelectronic-interaction correction of first order in $1/Z$ is treated
within the Breit approximation. Higher orders in $1/Z$ are partially taken into
account by incorporating the screening potential into the zeroth-order
Hamiltonian. The most accurate to date theoretical predictions for the nuclear
recoil contribution to the bound-electron $g$ factor are obtained.
