Re: Need a Prop for 1959 Westbend Outboard.
A fine looking motor.
16 and 18 hp use a 8 1/2 X 8 1/2 prop. 16 and 18 hp motors appear in 59-63 and possibly 16 in
56,57 at least model # 16902, 16912 in 57 and 16941 ,16951 in 57.
Pretty sure the 20 also uses an 8 1/2 X 8 1/2. at least the 66,67 20 hp Chryslers use 8 1/2 X 8 1/2.West Bend was purchased by Chrysler in 65.69-76 Chrysler uses the same drive pin 3/16 X 1 5/16 and same pitch 8 1/2 X 8 1/2.Whether the same shaft is a guess. I don't have 68 info.
Fairwinds Marina claims to have every Chrysler part.
