I have a 1965 Chrysler 55 hp outboard engine.
I want to know what other Chrysler outboard engines have a lower unit that I could use on my engine.
I would like to know the years as well as the horse power of engines that fit the description explained in the question above.
Thanks.

. My book does not so the 55hp offered till 1967. The 55hp engine from 1967 thru 1976 should interchange as all use the same impeller and seal kits.

Thank you very much, your answer is just what I needed to know.
John.
