Prop pitch

What is the standard prop pitch for my 1991 Starcraft 19 ft Eurostar with a 4.3L Mercruiser and Alpha outdrive ?

There isn't a really ideal prop.one or more props may be needed if you often carry heavy loads or do water sports .
If there is a prop on there look near the base of the blades or under the nut for numbers.
