Hi John your motor was made by Chrysler Marine. It was made from 1965-1967. I will just take a guess yours is a 66 model. It is a 9.2hp and uses a 50:1 ratio.
I believe I have the same motor and am looking for a prop. I just bought it and it didn't have a prop or anything attached to the shaft. Do you have any idea where I can get prop/parts. You can email me direct at kjcleasby@charter.net<br /><br />Thanks in advance!!!
