Merc Stainless Steel Prop

[jdidonato]

Hi everyone,
I have a prop question?
I have a Stainless Steel 13 1/2 X 21 Merc prop from a 21' Regal runabout. The runabout has a alpha drive. Would anyone know if this prop would fit on a 1978 115HP Merc outboard.

Thanks
Joe

Look up the props at the prop store check part numbers,diameter and features.
I would suspect the outdrive may be a bigger gearcase.

Sorry...won't fit. The Merc O/B has a 4 1/4" gearcase. Mercruiser Sterndrives are 4 3/4".
