Thanks Rapple for posting this table as this confirms what I assumed was the original engine config of 327F 210 hp w/ paragon 2.5:1 trans. My replacements by the PO are 3 blade dynajet bronze 21x22 and a GM350 reported to be 250 hp.
It seems this table is a bit older as it lists the 431 MEL but not the 427's which is what I am trying to approximate.
according to the packing slip from 1966, there have been chris craft 426 300hp in our boat
so then the previous owner replace enginer and the propellers to 21x23 to Detroit diesel serie 8.2l she seems to go nicely with these 26 knots
Now I wait for the new ones these propellers are new jearsy and soon in my hand the season is almost over but I'll try them before we take the boat up
