I have a Nitro 882nx DC with a Merc OptiMax, and I am beginning to wonder
if
I can get a bit better performance with a different prop.

Currently runs about 60 in good water with the bow trimmed up, but Nitro's
literature suggests 64-65 can be expected.

Ya'll know where to start looking for information regarding propping out a
boat properly?

Do you really want to spend several hundred dollars for an extra 4mph? As
Bob mentioned, I'm betting 64mph is under _ideal_ conditions.
