Mercury Outboard 150hp Exhaust Manifold Cover Water Jacket 60433 75778 1023-5068 Lower Unit This would have been used

This would have been used only on the extremely early MerCruiser I first year models (1963-1966) (110hp

Center hole diameter: 5/8"

but the future parts looks slightly different however it is likely that the thru-bolt holes are all in the same location throughout the years)

This will not work with electric start

so more details for compatibility will be added later for those of you that don't have access to the parts diagrams
