According to DISCOUNT MARINE PARTS, Wizard didn't have a 9.2 hp motor in 1966. They are only listed from 1969 to 1972. Do you have a model number? It should be COC-6609A96, COC-6609A07, or COC-6609A17. They were made by Chrysler at the time for Western Auto, so it's a good bet that a Chrysler motor of similar hp. and age would have a lower that would work with yours.
