I’m surprised we haven’t confused anybody yet concerning the "old" 18hp. The isolated drive shaft chamber first appeared on the 1958 35hp Lark/Super Quiet, and the 50hp, plus the redesigned 10hp. The 18/20/25hp didn’t get it till 1968. Until then, the crankshaft end stuck down into the nasty exhaust/water environment. That’s why they used that baffle plate to shield it—which didn’t do much good.
