    The FD11and the QD 18 (18hp and 10hp respectively) from 1957 share the same gear set PN# 377147, share the same gear case shell PN# 379216 and the same drive shaft PN# 308615. It is a direct bolt up, simply change the prop.

    This is not the case for ALL 10s and 18s, but for the 1957 lineup it is.
