The nuclide ${}^{87}$Mo with $A=4n+3\mathrm{}$ and $T_z$=3/2 was reinvestigated via its $\beta$-delayed proton decay with $p-\gamma$ coincidence. The proton branching ratios in the decay of ${}^{87}$Mo populating the first 2${}^{+}$, 4${}^{+}$, and 6${}^{+}$ excited states in ${}^{86}$Zr have been measured to be (11$\pm$6)%, (2$\pm$1)%, and (2$\pm$1)%, respectively, which revise the previous results.
