New Df 90 prop

I bought a 09 DF 90 .I am putting it on a 470 Joker boat.As you probably know,it comes
without a prop,so I need to buy one. I guess that best options would be 14x20 or 14x22 stainless. The boat is pretty small and I want to use it for criusing.50-70 km/day in Croatia
for the next two weeks :-). Would a 23 inch be even better?

Thank you

I've found that prop selection is best accomplished by trial and error.

Even theoretically identical boats may run best with differing props.

See if the you can find a shop that will let you trial some different props, and select based on actual performance.

I saw this message a bit to late (see my previous reply to your message, sorry). So you did buy him? I've got some experience now with different props now on m Joker:
13 3/4 x 19 3 blades, 80km/h 6300rpm 1 person, 75 km/h 6100 rpm 4 persons
13 3/4 x 21 3 blades, 85km/h 6300rpm 1 person, 80 km/h 6100 rpm 4 persons
13 1/4 x 24 4 blades stainless, 90km/h 5300 rpm 1 person
13 1/4 x 20 3 blades stainless, 75km/u in the ref. limiter.

I'm waiting for a 13 3/4 x 22 stainless 4 blades prop from Yamaha now, fit's also and are better "cupped" (hope you write it like that :-). This should be the one I need.
