Bombard DB500#Yamaha F90 propeller pitch

[themann]

I have a Bombard DB550 (18ft) powered by a Yamaha 90hp 4 strokes. I<m prsently using a propeler with a pitch of 17. The boat is perfect when loaded (I really really load it) but I start to use it for fun and the motor turn way to fast, WOT of 6000-6100rpm and my cruse rpm is around 5200-5500rpm. I need to get a proper propeller for this application and I<m looking at one with a pitch of 21, is it a good choice or should I go with a pitch of 19^

Thanks you

I have both a 17 inch and 19 inch for my SR. TBH I stay with the 17 mostly for better hole shot as it's flooding hull is open.
