Suzuki DF50 best prop size / pitch

[snowsports1]

Hi can you recommend the best all round prop size and pitch for a light loaded 4.8m rib with a DF50 please.

I ran a 15" on my 4.5m Avon Adventure. It still managed 6k revs when light loaded. (I believe the range is 5900-6400rpm)

I was tempted to go 16"......but then I sold it.

I have a 10.5" 13 degree pitch at the moment which sounds too small? I have just bought the rib.

It depends on what you use it for.?

Have you had chance to test it yet.?

It also seems your running a smaller prop than I did.

I used a 11 1/4" x 15" aluminium 3 blade prop.

I tried it but only in the hamble river, seemed to rev quite high 4000 revs for 8 knots approx. I checked with pacer marine today and they said it was the right prop for the engine. They said anything larger would take ages to accelerate

I am using it for a light 4.8m rib, family boating with occasional ski for small kids
