I have an Alpha that's half way in between. It's 1987-89. Came with a 5.0 on a 23-24 boat. I bought the entire motor and outdrive this year from a guy who was getting a larger motor. Kept my outdrive because it's a different size boat. It's supposed to be fresh water from Texas-Ark. lakes. Motor works fine - can't see any reason why the outdrive wouldn't.
