A 1957 QD has the sturdy "5-bolt" gearcase used on 12, 15, 18, 20, and 25 hp engines (with evolution), but I imagine it suffers from weaker wrist pins…
The 9.5 has an evolved version of the 5.5 and 7.5 "4-bolt" gearcase, which while sleeker/faster, was less sturdy (can’t say as I’ve heard about gearcase complaints on the 9.5, but plenty of complaints about the tight quarters under the hood)
