Welcome to the forum rstimy !
Looks like a 1976 CV16.
I have a Baystar on my CV16, the Seastar would work but not if you want to lift motor
Is you Merc a old style 2 tilt & trim cylinders ?
Or
The newer style with 3 T & T cylinders ?
The Baystar will fit the newer style motors, the older style will need some modification to fit.
The last picture is the newer style T & T system.
