Depends on your boat, engine, etc.
I am working with Ken @ propgods.com to help me find the right prop for me this upcoming season.
I suggest checking him out.
He is one of the premier prop guys in the country. based out of Fl.
One of the few places that will let you try a prop, then return it and try another if it does not meet your needs (rpm, etc).
I SERIOSULY doubt you need a 4blad for that boat and engine.
get a good SS in a pitch size to give you MAX rpm reco'd for your engine.
My range happens to be 4500-5500 for my engine, and am at 5000, but the correct rpm (in order not to lug engine and ultimately harm) is 5600-5800 with a very light load.
This way when loaded up to normal capacity, it will be right at 5500.
